Jarrell Miller
Jarrell Miller (born July 15, 1988) is an American professional boxer who competes in the heavyweight division.[1] Known by the nickname "Big Baby," he stands at 6 feet 4 inches tall and fights in an orthodox stance.[1] A native of Brooklyn, New York, Miller began boxing at age 16 and made his professional debut on July 18, 2009, defeating Darius Whitson by third-round technical knockout.[2] Prior to boxing, he had a successful kickboxing career, compiling a 22–2 record.[3] Miller's professional boxing record stands at 26 wins, 1 loss, and 2 draws, with 22 of his victories coming by knockout.[4] He captured regional titles early in his career, including the vacant WBO NABO heavyweight championship in 2016 by stopping Nick Guivas in the first round, and the NABA heavyweight title later that year via seventh-round stoppage of Donovan Dennis.[5][6] Among his notable victories are knockouts of former world champions Tomasz Adamek in 2018 and Mariusz Wach in 2019, which positioned him as a top contender.[7] His most recent bout was a majority draw against former unified heavyweight champion Andy Ruiz Jr. on August 3, 2024, at BMO Stadium in Los Angeles.[4] Miller's career has been overshadowed by multiple doping violations. In 2014, while competing in kickboxing, he received a nine-month suspension after testing positive for a banned substance.[8] A planned 2019 title challenge against Anthony Joshua for the WBA (Super), IBF, WBO, and IBO heavyweight championships was canceled after Miller failed three drug tests for performance-enhancing drugs, including GW1516, human growth hormone, and EPO.[9][10] He faced another positive test in 2020, leading to a two-year suspension from the New York State Athletic Commission.[11] Miller returned to the ring in late 2022, winning two fights before suffering a loss to Daniel Dubois in December 2023 and drawing with Ruiz in 2024.[4] In November 2025, Miller was photographed with promoter Eddie Hearn, suggesting a reconciliation and potential new promotional deal.[12]Background
Early life
Jarrell Miller was born on July 15, 1988, in the Bedford-Stuyvesant neighborhood of Brooklyn, New York, to parents of mixed Caribbean and Latin American heritage, including Haitian and Belizean descent.[13][14] He lived in the United States, Canada, and Belize, moving to Belize at age two for five years.[13] Growing up in the tough Bed-Stuy area, Miller faced significant exposure to street violence during his childhood, including a personal attack that prompted him to seek ways to protect himself.[14][15] At age 14, he began training in Muay Thai as a means of self-defense and to build personal resilience amid his challenging environment.[14][16] Two years later, at 16, he transitioned to boxing to further channel his aggression and pursue structured combat sports involvement.[14]Amateur career
Miller began his amateur boxing career around 2005, training at the renowned Gleason's Gym in Brooklyn under coach Harry Keitt.[17] One of his key achievements came in 2007 when he competed in the New York Daily News Golden Gloves tournament in the heavyweight division, representing Gleason's Gym.[18] He advanced to the final held at Madison Square Garden but lost on points (4-1) to Tor Hamer of Kingsway Boxing Club, earning a silver medal.[15] Miller's overall amateur boxing record is reported as 10-1, with his limited participation stemming from his concurrent professional kickboxing career.[19] In 2009, at age 21, Miller decided to turn professional, driven by financial necessities and the income opportunities in kickboxing that made extended amateur boxing less viable.[20][19] This transition marked the end of his brief but promising amateur phase, setting the stage for his professional pursuits.Kickboxing career
Key bouts and achievements
Miller made his mark in professional kickboxing through his participation in the World Combat League (WCL), where he represented the New Jersey Tigers and secured a notable victory over K-1 veteran Pat Barry by technical knockout on May 3, 2008, at the WCL Eastern & Western Conference Finals in San Antonio, Texas.[21] This win highlighted his early potential in the heavyweight division. His breakthrough in major international promotions came in 2012 with K-1. On September 10, 2012, at the K-1 World Grand Prix 2012 in Los Angeles, Miller defeated Jack May by knockout in the first round at 2:42, showcasing his striking power.[22] Just over a month later, on October 14, 2012, he advanced in the K-1 World Grand Prix Final 16 in Tokyo by winning a unanimous decision over Arnold Oborotov after three rounds.[23] Miller joined the Glory Kickboxing promotion in 2013, competing as a heavyweight contender in high-profile events. Notable victories included a third-round knockout of Daniel Sam at Glory 12 on November 23, 2013, in Erie, Pennsylvania, and a split decision win over Sergei Pavlovich at Glory 14 on March 8, 2014, in Zagreb, Croatia.[24][25] His tenure there solidified his reputation among elite heavyweights before his final kickboxing bout in 2014.Doping suspension
In August 2014, Jarrell Miller tested positive for methylhexaneamine, a banned stimulant, in a post-fight urine sample collected after his unanimous decision loss to Mirko Cro Cop at Glory 17 on June 21, 2014.[9][8] The substance, also known as dimethylamylamine, was prohibited by the World Anti-Doping Agency since 2010 due to its performance-enhancing effects and potential health risks.[8] The California State Athletic Commission (CSAC) imposed a nine-month suspension on Miller, effective from August 1, 2014, to May 1, 2015, along with a $2,500 fine.[8][26] This marked Miller's first documented doping violation in combat sports, drawing significant scrutiny to his career trajectory in kickboxing.[9] The suspension effectively ended Miller's tenure with Glory Kickboxing, as he did not compete in the promotion again following the penalty.[26] In the aftermath, Miller shifted his focus exclusively to professional boxing, continuing his activity in the sport without interruption from the kickboxing ban. While Miller did not publicly comment on the 2014 incident at the time, later reflections on his doping history emphasized unintentional use for recovery rather than performance enhancement.[27]Professional boxing career
Debut and early fights (2009–2015)
Jarrell Miller made his professional boxing debut on July 18, 2009, defeating Darius Whitson by first-round knockout at the Plattduetsche Park Restaurant in Franklin Square, New York.[7] Following a nearly two-year hiatus, Miller returned in May 2011 with another first-round knockout over Isaac Villanueva at the Roseland Ballroom in New York City.[7] He maintained his momentum in 2012, securing first-round stoppages against Donnie Crawford in Queens and Tyrone Gibson at the Roseland Ballroom.[7] In January 2013, Miller faced Joey Dawejko in a scheduled six-round bout at Mohegan Sun Casino in Uncasville, Connecticut, resulting in a draw by majority decision after a competitive encounter.[7] He rebounded later that year with three consecutive first-round knockouts, stopping Tobias Rice in Queens, Willie Chisolm in Maryland, and Sylvester Barron in New York City.[7] Miller's 2014 campaign included three more first-round triumphs: over Jon Hill in Pennsylvania, Joshua Harris in Brooklyn, and Rodricka Ray on Long Island.[7] By the end of that year, his record stood at 10-0-1 (9 KOs), with most bouts appearing on undercards for regional promotions in the New York area and nearby states.[7] Throughout this period, Miller's activity remained sporadic, with notable gaps between fights stemming from his efforts to balance professional boxing with ongoing kickboxing commitments, as he had competed in both disciplines concurrently for several years following his kickboxing successes.[20] In 2015, he fought five times, all ending in first-round knockouts against opponents including Aaron Kinch, Raymond Ochieng, Damon McCreary, Excell Holmes, and Akhror Muralimov, primarily at casino venues across the United States.[7]Rise to contention (2016–2018)
In 2016, Jarrell Miller began his rise in the heavyweight division by capturing regional titles that established him as a contender. On January 22, he defeated Donovan Dennis by technical knockout in the seventh round (2:31) at Casino Del Sol in Tucson, Arizona, to win the interim WBA-NABA heavyweight title.[28][29] Less than four months later, on May 27, Miller unified his titles by stopping Nick Guivas via technical knockout in the second round (1:26) at Seneca Niagara Resort and Casino in Niagara Falls, New York, claiming the vacant WBO-NABO heavyweight belt, which he held through December 2017.[5][30] Miller's momentum continued into 2017 with victories over experienced opponents. On July 29, he overcame former title challenger Gerald Washington by eighth-round retirement at Barclays Center in Brooklyn, New York, as Washington cited injury after absorbing heavy punishment.[31] Four months later, on November 11, Miller secured a ninth-round technical knockout (1:02) against Mariusz Wach at the same venue, halting the bout due to Wach's hand injury amid mounting damage.[32] The following year, Miller solidified his contender status with high-profile wins. On April 28, 2018, he outpointed Johann Duhaupas via unanimous decision (119-109, 119-109, 117-111) over 12 rounds at Barclays Center, earning a mandatory position as the WBA heavyweight title eliminator.[33] In October, Miller achieved an upset by knocking out former world champion Tomasz Adamek in the second round at Wintrust Arena in Chicago, Illinois, dropping the 41-year-old Pole twice before the referee intervened.[34] He closed out the year on November 17 with a fourth-round knockout over Bogdan Dinu at Kansas Star Arena in Mulvane, Kansas, flooring the Romanian twice in the final round to push his undefeated record to 23-0-1.[35]Doping violations and cancellations (2019–2020)
In April 2019, Jarrell Miller tested positive for the banned substance GW1516 in a sample collected on March 20 by the Voluntary Anti-Doping Association (VADA), ahead of his scheduled heavyweight title challenge against Anthony Joshua on June 1 at Madison Square Garden. Subsequent VADA tests in April confirmed additional positives for erythropoietin (EPO) and human growth hormone (HGH), marking three failed tests in total. These violations led to the New York State Athletic Commission revoking Miller's boxing license, resulting in the immediate cancellation of the high-profile bout, which had been promoted as Joshua's U.S. debut. The World Boxing Association (WBA) responded by imposing a six-month suspension on Miller and removing him from their heavyweight rankings, effective from April 2019.[36] The incident also caused significant financial repercussions, including the forfeiture of an estimated $7 million purse for the Joshua fight and at least $3 million from a multi-fight deal with DAZN, which included two guaranteed comeback bouts. In a public statement, Miller admitted he had "messed up" but denied knowingly ingesting the substances, attributing the positives to accidental exposure through tainted supplements and a stem cell injection for an elbow injury.[10][37] In June 2020, Miller faced another setback when he tested positive for GW1516 during out-of-competition testing by VADA, just weeks before his planned comeback fight against Jerry Forrest on July 9 in Las Vegas.[38] The Nevada State Athletic Commission (NSAC) placed him on temporary suspension, leading to the bout's cancellation and his removal from the card.[38] On December 2, 2020, the NSAC formally issued a 24-month suspension for the violation, backdated to January 2020, which was set to expire in January 2022, with a possible six-month reduction contingent on completing an approved anti-doping education program.[11] Following this second infraction, the World Boxing Council (WBC) expelled Miller from their rankings.[39] Miller again issued a public apology, reiterating claims of unintentional ingestion via contaminated sources and expressing outrage at the repeated accusations.[40]Suspension period and return preparations (2020–2022)
Following his positive drug test in June 2020 for the banned substance GW1516, Jarrell Miller was placed on temporary suspension by the Nevada State Athletic Commission (NSAC). In December 2020, the NSAC formally imposed a 24-month suspension, backdated to the date of the failed test, making Miller ineligible to compete until June 2022. The terms included a provision for a potential six-month reduction if Miller submitted to and passed at least two random drug tests administered by the Voluntary Anti-Doping Association (VADA) during the suspension period.[11][41] In March 2022, Miller appeared before a five-member NSAC panel seeking an additional reduction beyond the initial provision, but the commission unanimously denied the request, upholding the suspension's end date of June 16, 2022. This partial success in the original terms—through compliance with random testing—allowed Miller to regain eligibility shortly thereafter, though he remained barred from licensed bouts in Nevada and other jurisdictions enforcing reciprocal suspensions until clearance. During this period, Miller maintained strict anti-doping protocols, including ongoing VADA monitoring, to demonstrate compliance and facilitate his reinstatement.[42][43] To prepare for his return, Miller relocated his training base to South Florida in late 2021, linking up with renowned trainer Kevin Cunningham at the 5th Street Gym. This move emphasized a disciplined regimen focused on technical refinement, cardiovascular endurance, and weight management, with Cunningham stressing clean nutrition and avoidance of any substances that could trigger positive tests. Miller underwent regular VADA testing and nutritional oversight to rebuild trust with commissions and promoters, aiming for a ring return by mid-2022. He expressed determination to prove his legitimacy, stating that the suspension had been a "wake-up call" for cleaner practices.[44][45] Miller's first bout following the suspension came on June 22, 2022, against Ariel Esteban Bracamonte in Buenos Aires, Argentina, a six-round unanimous decision victory despite Miller being deducted a point for a low blow in the fourth round. Weighing a career-high 340 pounds, he showed rust but controlled the distance with pressure and body work. Less than a month later, on July 22, 2022, in Murfreesboro, Tennessee, Miller secured a fourth-round TKO over Derek Cardenas, dropping his opponent twice and prompting a stoppage. These low-level wins marked the beginning of his post-suspension record at 2-0, serving as tune-ups to shake off inactivity while adhering to anti-doping standards.[46]Comeback fights (2023–2024)
Miller returned to the professional boxing ring on March 18, 2023, facing Australian veteran Lucas Browne in a scheduled 10-round heavyweight bout at The Agenda in Dubai, United Arab Emirates. Despite a competitive start where Browne landed heavy shots in the early rounds, Miller turned the tide with relentless pressure, dropping Browne in the sixth round before the referee stopped the fight at 2:36 due to accumulated damage, securing a technical knockout victory. This win improved Miller's record to 26-0-1 (22 KOs) and marked his first professional bout since 2018.[47][48] On December 23, 2023, Miller stepped up against the undefeated British heavyweight Daniel Dubois on the undercard of the Anthony Joshua vs. Otto Wallin event at Kingdom Arena in Riyadh, Saudi Arabia. In a grueling 10-round contest, Miller showed resilience, absorbing heavy punishment while landing counters, but Dubois' power proved decisive in the final round, where a barrage of punches forced a stoppage at 2:52 of the 10th, handing Miller his first professional defeat by technical knockout. Miller's record fell to 26-1-1 (22 KOs) following the loss.[49][50] Miller rebounded in 2024 with a high-profile matchup against former unified heavyweight champion Andy Ruiz Jr. on August 3, at BMO Stadium in Los Angeles, California, as part of the Terence Crawford vs. Israil Madrimov undercard. Over 12 rounds, Miller outworked Ruiz in the later stages, pressing forward with volume punching against a fading opponent, but the judges rendered a majority draw with scores of 116-112 for Miller and 114-114 twice. The result maintained Miller's record at 26-1-2 (22 KOs) and drew criticism for potentially favoring Ruiz's early activity.[51][52]Recent developments (2025)
In early 2025, Jarrell Miller was slated to face Michael Hunter in an all-American heavyweight bout on September 11 in Las Vegas, serving as the co-main event to the anticipated Canelo Alvarez vs. Terence Crawford superfight and broadcast on Netflix.[53] The matchup fell apart due to unresolved legal and regulatory issues, with promoter Don King issuing a cease-and-desist letter to TKO Group Holdings over the announcement, leading Miller to publicly confirm the cancellation on social media while expressing frustration over the handling of the bout.[54][55] Later that year, negotiations advanced for Miller to challenge Derek Chisora on December 13 at the Co-op Live Arena in Manchester, United Kingdom, as part of Chisora's potential 50th and final professional fight.[56] The talks ultimately collapsed amid disputes, with Chisora's promoter Frank Warren opting instead for a matchup against Dillian Whyte, prompting Miller to accuse parties involved of sabotaging the deal in a post-fight interview.[57][58] In November 2025, Miller reunited with promoter Eddie Hearn of Matchroom Boxing, marking a significant shift after years of tension stemming from Miller's 2019 doping violation that canceled a bout with Anthony Joshua.[12] The partnership, confirmed through public appearances and statements, positions Miller for high-profile opportunities, including speculation around a rematch with Joshua.[59] As of November 2025, Miller's professional record remains 26-1-2 (22 KOs), and he continues intensive training in Florida for an opponent to be announced.[1]Career records and accomplishments

Kickboxing record
Jarrell Miller competed professionally in kickboxing from 2012 to 2014, amassing a record of 22 wins and 2 losses, with 10 knockouts.[3] His career spanned promotions including K-1 and Glory, with earlier appearances in the World Combat League (WCL), though detailed records for minor WCL events remain incomplete and are primarily drawn from promotional archives.[3][61] No further kickboxing activity occurred after 2014, as Miller shifted focus to professional boxing amid a doping suspension.[3] The following table summarizes select documented bouts, highlighting key results from major events; a full chronological list is not comprehensively available due to archival limitations in pre-2012 promotions.| Date | Opponent | Result | Method | Round | Event | Location |
