Tanner Boser
Tanner Boser (born August 2, 1991) is a Canadian professional mixed martial artist who competes as a heavyweight under the nickname "The Bulldozer."[1] Standing at 6 feet 2 inches tall with a 75-inch reach, he fights in an orthodox stance and trains with Shaved Bears MMA.[1] With a professional record of 22 wins, 10 losses, and 1 draw—including 12 knockouts or technical knockouts, 2 submissions, and 8 decisions—Boser is a two-time Unified MMA Heavyweight Champion.[1][2] Boser began his professional MMA career in 2012, quickly establishing himself on the Canadian regional scene.[1] He captured the Unified MMA Heavyweight Championship for the first time in 2015 by defeating Victor Valimaki via TKO and defended it several times through 2016 before winning the title a second time in 2019 against Jared Kilkenny via TKO.[1][2] During this period, he also competed internationally, including a stint in the Absolute Championship Berkut (ACB) promotion in Russia from 2017 to 2018, where he compiled a 3-3 record.[1] In October 2019, Boser made his Ultimate Fighting Championship (UFC) debut at heavyweight, defeating Daniel Spitz by unanimous decision.[1] Over the next four years, he compiled a 5-5 record in the promotion, with standout victories including a second-round knockout of Philipe Lins in 2020 and a first-round knockout of Ovince Saint Preux in 2021.[1][3] He later moved to the light heavyweight division, losing to Ion Cuțelaba via first-round TKO in April 2023 and winning a unanimous decision over Aleksa Camur in August 2023, after which his contract expired.[1][3] Following his UFC tenure, Boser returned to the regional circuit, securing a third-round TKO win over Vinicius Moreira at UAE Warriors 60 on June 13, 2025.[1] In December 2024, he signed an exclusive contract with the Global Fight League (GFL), a team-based MMA promotion.[4] He was subsequently drafted 20th overall to Team London in the GFL's inaugural draft on January 24, 2025.[5][6] Although GFL's debut events planned for May 2025 were cancelled, the promotion has teased a potential launch in 2026.[7][8]Early life and background
Family and upbringing
Tanner Boser was born on August 2, 1991, in Bonnyville, Alberta, Canada, a small town in the northeastern part of the province known for its rural landscape and proximity to oil industry operations.[1][2][9] He grew up in this community of approximately 7,000 residents, where the local economy is heavily influenced by the energy sector.[10] Boser was raised by his mother, Linda Boser, who owned Hi-Energy Fitness and MMA studio in Bonnyville, and his father, who worked in the oil fields.[11][10] This family environment provided early access to fitness facilities, fostering an active lifestyle from a young age. Boser's upbringing was non-traditional, as he was homeschooled until entering high school, which allowed flexibility but also meant adjusting to a more structured social setting later on.[12] He has a younger brother, Landon Boser, who is also a professional mixed martial arts fighter based out of Bonnyville.[13][14] The siblings share a close bond, shaped by their shared rural roots and involvement in combat sports.Education and early interests
Boser was raised in the small town of Bonnyville, Alberta, Canada, where his mother owned a local gym that exposed him to physical fitness and conditioning from a young age. This environment fostered his early interest in general physical activities, such as weight training and cardio exercises, emphasizing health and strength as family values. His father's role as an oil field worker further shaped Boser's work ethic, instilling discipline through exposure to demanding manual labor. Following his high school graduation in Bonnyville, Boser entered the workforce by driving a truck to deliver supplies to oil field companies, a path directly influenced by his father's career. This job provided financial stability during his late teens and early twenties but highlighted his growing inclination toward physically intensive pursuits. Later, while based in Edmonton, he worked as a bouncer at a strip club for approximately five years, a role that honed his awareness of personal security and physical presence amid challenging environments.[15] Before fully committing to a professional path in combat sports, Boser briefly explored a career in emergency services by enrolling in an Emergency Medical Technician course around 2016, aiming to become a paramedic. This training was short-lived, however, as his passion for competitive physical endeavors ultimately drew him back to full-time dedication elsewhere.[16]Introduction to martial arts
Tanner Boser's introduction to martial arts began in his youth in Bonnyville, Alberta, where his mother's ownership of a local gym provided early exposure to fitness and physical activities. At the age of 11, he started training in Shito-ryu karate, inspired by friends and the competitive aspect of the discipline. He dedicated himself to the sport through his teenage years, participating in competitions and advancing steadily until earning his black belt in his late teens.[10][2] Following high school, Boser paused his martial arts training to focus on full-time work, including driving trucks, which led to a period of reduced physical activity. His interest reignited upon encountering a King of the Cage event in nearby Cold Lake, prompting him to explore mixed martial arts. With primarily his karate foundation, he began incorporating grappling arts, progressing to Brazilian jiu-jitsu and achieving a purple belt level. This foundational work in striking and submission techniques prepared him for competitive fighting.[10][2] In 2013, Boser relocated from Bonnyville to Edmonton, Alberta—a three-hour drive—to pursue MMA training more intensively while working as a bartender and later a bouncer. This move allowed access to better facilities and coaching, building on his karate and jiu-jitsu base through consistent sparring and skill development. With limited formal amateur bouts due to regional challenges in arranging them, Boser transitioned directly to professional competition, making his pro debut on October 5, 2012, at Unified MMA 13, where he secured a third-round TKO victory.[17][10][1][18]Professional MMA career
Early career and regional promotions
Boser made his professional mixed martial arts debut on October 5, 2012, at Unified MMA 13 in Edmonton, Alberta, Canada, defeating Mike Cobey by technical knockout via punches at 3:44 of the third round.[1] Drawing on his foundational karate background and basic Brazilian jiu-jitsu skills, he entered the heavyweight division without extensive formal MMA training, relying initially on self-directed preparation through online resources and local sparring. Following this victory, Boser secured a submission win via rear-naked choke against Dell Knebush in the first round at Unified MMA 16 on June 21, 2013, also in Edmonton, extending his record to 2-0.[1] After these initial successes, Boser relocated to Edmonton full-time to intensify his training at local camps, balancing sessions with part-time bartending to support his career. He continued competing in regional promotions such as King of the Cage and Xtreme Fighting Challenge, notching knockout victories including a first-round TKO over Matthew Swimmer at KOTC: Anger Therapy on October 25, 2013, in Stony Plain, Alberta.[1] These performances helped build a 6-0 record, showcasing his striking power with multiple finishes by knockout or submission in Canadian-based events. Boser suffered his first professional loss on March 20, 2015, at Unified MMA 22 in Edmonton, where veteran Tim Hague knocked him out with a punch just six seconds into the first round.[1] He rebounded quickly with a first-round TKO over Jared Henderson at KOTC: Mach 3 on June 12, 2015, in Calgary, Alberta, followed by a second-round TKO via leg kicks against Victor Valimaki at Unified MMA 24 on September 25, 2015, in Edmonton, bringing his record to 8-1.[1] In 2016, Boser avenged his loss to Hague with a second-round knockout via elbows at their rematch on March 4 at Unified MMA 26 in Enoch, Alberta, and added decision wins over Tony Lopez, Joe Yager, and Rakim Cleveland in subsequent Unified MMA events, all held in Edmonton.[1] His only other setback in this period came via unanimous decision loss to Kazbek Saidaliev at WFCA 17: Grand Prix Akhmat on April 9, 2016, in Grozny, Russia, marking his initial international experience outside Canada.[1] By the end of 2016, Boser had compiled an 11-2 record primarily through regional bouts in Alberta, solidifying his base in Edmonton-based training environments.Unified MMA Heavyweight Championship reign
Boser captured the vacant Unified MMA Heavyweight Championship on March 28, 2014, at Unified MMA 18 in Edmonton, Alberta, defeating Nick Campbell by rear-naked choke submission in the second round at 4:53.[19] He made his first successful defense on September 26, 2014, at Unified MMA 20, stopping Jordan Tracey via TKO (punches) in the third round at 2:39. Boser's initial reign ended on March 20, 2015, at Unified MMA 22, when he was knocked out by Tim Hague in the first round at 0:06, resulting in the loss of the title.[20] Following additional victories outside of title contention, including a rematch knockout of Hague on March 4, 2016, at Unified MMA 26 via elbows in the second round at 2:30, Boser returned to challenge for the heavyweight crown.[1] He won the title for the second time on June 3, 2016, at Unified MMA 27, earning a unanimous decision victory over Tony Lopez after five rounds (50-45, 50-45, 49-46).[21] Boser made two successful defenses during his second reign. On September 30, 2016, at Unified MMA 28, he defeated Joe Yager by unanimous decision over five rounds.[22] He followed this with another unanimous decision win against Rakim Cleveland on December 16, 2016, at Unified MMA 29, also going the full five rounds.[23] Boser continued to hold the title while competing internationally and made an additional successful defense on May 24, 2019, at Unified MMA 37, defeating Jared Kilkenny via TKO (leg kicks) in the fourth round at 2:17.[24] He relinquished the Unified MMA Heavyweight Championship in 2019 upon signing with the UFC.[25]Ultimate Fighting Championship tenure
Tanner Boser made his Ultimate Fighting Championship (UFC) debut on October 18, 2019, at UFC on ESPN 6 against Daniel Spitz, securing a unanimous decision victory after three rounds to earn his first win in the promotion.[1] This performance marked Boser's entry into the heavyweight division of the UFC, building on his prior success as the Unified MMA Heavyweight Champion in regional promotions.[2] Less than two months later, on December 21, 2019, at UFC Fight Night 165, Boser faced undefeated prospect Ciryl Gane and suffered his first UFC loss via unanimous decision over three rounds, with Gane dominating through superior striking and movement.[1] Boser rebounded in 2020, starting with a first-round knockout victory over Philipe Lins on June 27 at UFC on ESPN 12, earning the Performance of the Night bonus for his explosive punching power that ended the fight at 2:41.[1] He followed this with a second-round TKO win against Raphael Pessoa on July 25 at UFC on ESPN 14, using ground-and-pound to finish the bout at 2:36.[1] Boser encountered setbacks in late 2020 and 2021, losing a unanimous decision to veteran Andrei Arlovski on November 7 at UFC on ESPN 17 after a competitive three-round striking battle, followed by a split decision defeat to Ilir Latifi on June 5, 2021, at UFC Fight Night 189 (29–28, 28–29, 29–28).[1] He responded with a knockout win over Ovince Saint Preux on June 26, 2021, at UFC Fight Night 190, dropping his opponent with punches in the second round at 2:31.[1] However, Boser dropped two more decisions in 2022 and 2023—a split decision loss to Rodrigo Nascimento on September 17, 2022, at UFC Fight Night 210, and a first-round TKO defeat to Ion Cuțelaba on April 15, 2023, at UFC on ESPN 44, where he was overwhelmed by punches at 2:05.[1] Boser's final UFC appearance came on August 5, 2023, at UFC on ESPN 50 against Aleksa Camur in the light heavyweight division, where he earned a unanimous decision victory (30-27 across all cards) after outstriking and controlling the fight over three rounds, marking his last win in the promotion.[1] Over his UFC tenure from 2019 to 2023, Boser compiled a record of 5 wins and 5 losses, with three of his victories coming by knockout or TKO.[1] Following this bout, which fulfilled the terms of his contract, Boser became an unrestricted free agent as the UFC did not extend an offer to renew, allowing him to explore opportunities elsewhere.[26]Post-UFC developments
Following his departure from the UFC as a free agent after completing his contract in 2023, Tanner Boser signed an exclusive contract with the Global Fight League (GFL) on December 11, 2024, as part of a major roster announcement that included several former UFC fighters.[27] The GFL, a team-based MMA promotion, had planned its inaugural events for May 24 and 25, 2025, at the Shrine Auditorium in Los Angeles, with Boser drafted to Team London. However, on April 9, 2025, the promotion cancelled both debut cards due to financial issues involving a primary investor's failure to fulfill commitments, casting uncertainty over its future and leaving signed fighters like Boser without scheduled bouts.[28] Boser returned to action on June 13, 2025, in the co-main event of UAE Warriors 60 in Abu Dhabi, where he defeated Vinicius Moreira by TKO (retirement) at 1:55 of the third round after landing heavy strikes that prompted Moreira's corner to stop the fight.[29] This victory improved Boser's professional record to 22-10-1 and marked his first competition outside the UFC in nearly two years.[1] As of November 2025, Boser has not competed since the UAE Warriors bout and has no announced fights or new promotional affiliations, positioning him as an active free agent in the heavyweight division.[30]Fighting style and technique
Striking approach
Tanner Boser's striking approach as a heavyweight primarily revolves around his devastating knockout power, evidenced by 12 KO/TKO victories in his professional record of 22-10-1.[1] This offensive style leverages his physicality to deliver high-impact blows that have ended numerous bouts early, establishing him as a dangerous finisher in the division.[3] Central to Boser's arsenal are heavy punches, particularly overhand rights, which he uses to close distances and exploit openings against opponents.[31] He complements these with effective ground-and-pound when opportunities arise from knockdowns, raining down punches to secure stoppages.[32] His background as a karate black belt, achieved by age 18, informs this precise and powerful stand-up game. In terms of efficiency, Boser lands 4.70 significant strikes per minute with a 53% striking accuracy, metrics that highlight his ability to connect potently without excessive volume.[3] A prime example of this approach occurred in his 2020 UFC bout against Philipe Lins, where an overhand right dazed the opponent, followed by a rapid seven-punch combination that dropped Lins and prompted a referee stoppage at 2:41 of the first round.[31]Grappling and defense
Tanner Boser holds a purple belt in Brazilian jiu-jitsu, a rank that has contributed to two submission victories in his professional career, both via rear-naked choke against Dell Knebush in 2013 and Nick Campbell in 2014.[2][1] In the UFC, Boser demonstrates strong takedown defense, successfully stuffing 63% of opponents' attempts, which allows him to maintain fights in his preferred striking range.[3] His defensive wrestling emphasizes sprawls and underhooks to neutralize grapplers, as evidenced in bouts like his 2021 split decision loss to Ilir Latifi, where Boser limited effective ground control despite being taken down twice.[3][33] Boser absorbs 2.75 significant strikes per minute, a below-average rate for heavyweights that reflects his ability to evade damage both standing and during brief ground exchanges.[3] In UFC fights, he averages minimal ground control time—often under one minute per bout—and excels at escapes, quickly returning to his feet to avoid prolonged grappling positions, such as in his 2022 split decision loss to Rodrigo Nascimento where he survived multiple takedown attempts and reversals.[3][34] This approach underscores his strategy of using defensive grappling to neutralize threats and transition back to striking.[3]Evolution over career
Boser began his professional MMA career in 2012 with a foundation in karate, relying primarily on raw power and striking to secure early victories, though his grappling skills were initially limited due to a lack of formal MMA training or coaching prior to his debut.[10] Following his first win, he incorporated Brazilian jiu-jitsu training, which allowed him to expand his skill set with a submission victory in his second bout and marked the start of a more versatile approach in regional promotions.[35] Upon entering the UFC in 2019 as a heavyweight, Boser adapted to the elevated competition level by emphasizing improved cardiovascular endurance, enabling him to maintain output over longer durations and secure several decision wins through consistent pressure.[36] This evolution was evident in his matchup against Ciryl Gane, where he competed effectively in striking exchanges early on before the fight extended to a full three rounds, showcasing his growing ability to handle elite opponents at distance.[37] After departing the UFC in 2023 following the expiration of his contract, Boser continued refining his style in international promotions, returning to heavyweight and demonstrating enhanced sustained aggression in his 2025 victory over Vinicius Moreira, where he overwhelmed the opponent with relentless striking volume across three rounds to force a retirement via TKO.[38] This performance highlighted further maturation in his pacing and pressure application, contributing to an overall shift toward a more balanced heavyweight game that integrates his striking roots with improved conditioning and opportunistic grappling.[1]Personal life and legacy
Family and relationships
Tanner Boser maintains a close relationship with his younger brother, Landon Boser, who is also a professional mixed martial artist competing in the lightweight division.[35] Landon has pursued a career in MMA, holding a professional record of 1-0 as of November 2025, and the brothers share a family legacy in combat sports, with Landon additionally teaching jiu-jitsu at a local gym in Alberta.[13] Their bond is evident in shared family events, such as serving as pallbearers together at a relative's funeral, highlighting the supportive role of siblings in Boser's personal life.[14] Boser relocated from his hometown of Bonnyville, Alberta, to Edmonton in 2013 to pursue full-time MMA training, and he has resided there ever since.[17] This move allowed him to immerse himself in a larger training community while staying connected to his Alberta roots. In Edmonton, Boser has built a stable home base that supports his demanding career, occasionally referencing the challenges of maintaining personal routines amid frequent travel for fights.[39] Public mentions of Boser's partnerships include a long-term girlfriend, with whom he has navigated aspects of his professional life, such as social distancing during the COVID-19 pandemic.[40] While Boser keeps much of his family life private, he has noted the importance of familial support in his career, including from close relatives who attend his events and provide emotional backing.[16] This network helps him balance the rigors of training and competition with personal responsibilities.Public persona and media
Tanner Boser is known by the nickname "The Bulldozer," which originated during his early MMA career after his fourth professional fight. His trainer, Mitch Clark, proposed the moniker following a dominant performance, initially teasing it as "Dill Dozer" before settling on "Bulldozer" to reflect Boser's overpowering, relentless fighting style. The nickname has been in use for nearly a decade and has become synonymous with his aggressive approach in the cage.[15] In post-fight interviews, Boser often displays a candid and pragmatic personality, emphasizing preparation and execution over bravado. For instance, after his knockout win at UFC Vegas 4 in 2020, he described his strategy as a "slow burn," noting how leg kicks slowed his opponent before landing decisive strikes, while expressing satisfaction that his game plan had worked as intended. His responses frequently highlight a self-aware humility, such as basing his self-worth on performance inside the octagon rather than external validation, and he has shared stories of personal quirks like opening cans with his teeth due to a missing tooth, adding a dry, understated humor to his public image. Boser's traits of diligence and groundedness are evident in discussions of his routine, where he credits consistent training—up to seven hours daily, six days a week—for his success, alongside maintaining a simple lifestyle focused on family and fitness in Edmonton.[41][42][16] Boser maintains an active presence on social media, particularly Instagram under the handle @bulldozerboser, where he engages fans through humorous posts and direct interactions. He has trolled detractors in lighthearted exchanges, such as responding to a hater ahead of a 2020 fight by sharing a funny anecdote from Abu Dhabi, and fired back at critics questioning other fighters' motivations, defending the profession's demands. His online activity has led to viral moments, including revealing his teenage appearance in a long-circulating MMA meme and a candid rant against UFC sponsorship deals that offer no financial benefit to athletes, which resonated widely among fans. These interactions portray Boser as approachable and unfiltered, fostering a relatable connection with his audience beyond the ring.[43][44][45] Media coverage of Boser's career transitions has highlighted his optimism and adaptability. In December 2024, following his UFC release after a 5-5 record, Boser signed an exclusive contract with the Global Fight League (GFL), a team-based MMA promotion.[4] He was drafted 20th overall to Team London in the GFL's inaugural draft on January 24, 2025.[5][6] Although GFL cancelled its planned May 2025 debut events, the promotion announced in October 2025 that it is working on plans for a 2026 launch.[7][8] This development continues to draw attention to Boser's career evolution at age 34.Impact on Canadian MMA
Tanner Boser has played a key role in representing Alberta fighters within the Ultimate Fighting Championship (UFC), emerging as one of the province's most visible heavyweights on the global stage. Hailing from Bonnyville and basing his career in the Edmonton area, Boser has proudly carried the banner for Alberta during his UFC appearances, highlighting the region's growing MMA talent pool.[46][47] Boser primarily trains at the Little Sweatshop gym in Sherwood Park, Alberta, as a core member of the Shaved Bears MMA team, a respected Canadian training group under coach Jeff Montemurro. This facility, located near Edmonton, serves as a hub for regional fighters, where Boser contributes to the development of local talent through rigorous sparring sessions and shared training regimens. For example, he has directly supported emerging Alberta heavyweight KB Bhullar by providing high-level practice that prepared Bhullar for his own UFC pursuits.[48][49] In addition to his training involvement, Boser has aided Edmonton's MMA ecosystem by instructing kickboxing and MMA classes at local gyms, repaying the community that nurtured his early development while fostering the next generation of fighters. His efforts have extended to family, influencing his brother Landon Boser, a professional lightweight MMA fighter from the same Alberta roots, to enter the sport.[50][13] Through his sustained presence as a top Canadian heavyweight, Boser has elevated the visibility of the division domestically and internationally, inspiring increased participation and recognition for heavyweights from Canada. His path from regional promotions like Unified MMA to a multi-fight UFC contract underscores Alberta's contributions to the national scene, encouraging more fighters from the province to aim for elite levels.[47]Championships and accomplishments
Major titles won
Tanner Boser first captured the vacant Unified MMA Heavyweight Championship on March 28, 2014, at Unified MMA 18 in Edmonton, Alberta, Canada, by submitting Nick Campbell via rear-naked choke in the second round at 4:53.[19][1][51] This victory marked Boser's fifth professional win and established him as the promotion's heavyweight titleholder at age 23.[20] Boser lost the title in his first defense against Tim Hague on March 20, 2015, at Unified MMA 22, also in Edmonton, via first-round knockout.[52][53] He avenged the defeat in their rematch on March 4, 2016, at Unified MMA 26, securing a technical knockout victory over Hague with elbows in the second round at 2:30, which positioned him for another title opportunity.[54][55] Boser claimed the Unified MMA Heavyweight Championship for the second time on June 3, 2016, at Unified MMA 27 in Edmonton, defeating Tony Lopez by unanimous decision after five rounds with scores of 50-45, 50-45, and 49-46.[20][21][56] This win over the veteran Lopez (54-27-1 at the time) solidified Boser's status as a two-time champion in the promotion. He went on to make several successful defenses, including unanimous decision wins over Joe Yager on September 30, 2016, and Rakim Cleveland on December 16, 2016, a second-round TKO of Pat Walsh on March 17, 2017, and others, before vacating the title upon signing with the UFC in 2019.[1]UFC bonuses and rankings
Tanner Boser earned a single UFC bonus during his tenure with the promotion, receiving the Performance of the Night award for his second-round knockout victory over Raphael Pessoa at UFC on ESPN 14 on July 25, 2020.[57] This finish, which came via a series of punches at 2:36 of the second round, highlighted Boser's striking power and contributed to a streak of back-to-back knockouts earlier that summer. He has not received any Fight of the Night or other performance-based bonuses in his UFC career.[57] In the heavyweight division, Boser achieved his highest ranking of No. 15 following his knockout wins over Philipe Lins in June 2020 and Pessoa in July 2020, marking his entry into the official UFC top 15 for the first time.[58] This peak placement reflected a strong 3-1 start to his UFC heavyweight run, positioning him among established contenders.[59] Boser later moved to light heavyweight in 2023, where he competed twice but did not enter the divisional rankings.[3] Boser maintained top-15 status briefly into 2021, bolstered by a second-round knockout of Ovince Saint Preux in June, but subsequent losses impacted his standing significantly. A unanimous decision defeat to Andrei Arlovski in November 2020 dropped him from the rankings initially, and further setbacks, including a split decision loss to Ilir Latifi in June 2021 and a first-round TKO to Ion Cutelaba in April 2023, prevented any sustained return to ranked contention. These results contributed to his overall 5-5 UFC record and eventual release from the promotion in 2023.[9]Overall career highlights
Tanner Boser has established himself as a durable and versatile heavyweight contender in mixed martial arts, amassing a professional record of 22-10-1 as of November 2025, including 12 knockout or technical knockout victories, 2 submissions, and 8 decisions.[1] His finishing prowess, particularly in striking exchanges, has been a hallmark of his style, contributing to notable upsets against established opponents throughout his career.[2] Boser debuted in the Ultimate Fighting Championship (UFC) on October 18, 2019, at UFC on ESPN 6 in Boston, Massachusetts, where he secured a unanimous decision victory over Daniel Spitz in his promotional bow.[60] Earlier in his career, he captured the Unified MMA heavyweight title twice, first in 2014 and second in 2016, solidifying his status as a top regional prospect in Canada before transitioning to international promotions.[2] In 2020, Boser achieved a two-fight win streak within the UFC, defeating Philipe Lins by second-round knockout on June 27 and Raphael Pessoa by second-round knockout on July 25, both during the promotion's "Fight Island" events in Abu Dhabi.[1] Demonstrating resilience after a period of inactivity following his last UFC bout in 2023, Boser mounted a comeback victory on June 13, 2025, at UAE Warriors 60 in the United Arab Emirates, earning a third-round technical knockout over Vinicius Moreira via opponent retirement.[1] This win highlighted his enduring competitiveness at age 33. Boser's extensive travels have seen him compete professionally in nine countries, including Canada, the United States, Russia, Kazakhstan, Australia, England, and the United Arab Emirates, broadening his exposure across promotions like ACB and M-1 Global.[30] During his UFC tenure, he earned one Performance of the Night bonus for a standout finish.[2]Mixed martial arts record
