Incomplete pass

An incomplete pass in refers to a legal thrown by the that fails to be caught by an eligible offensive receiver before touching the ground or going , resulting in the play being ruled dead immediately. This outcome advances the down by one (e.g., from first to second down) without any yardage gained for the offense, and the ball is spotted back at the previous . According to NFL rules, a pass is deemed incomplete if the receiver does not secure control of the ball in their hands or arms prior to it touching the ground, while also establishing possession inbounds and performing an act common to the game, such as extending for additional yardage or tucking the ball away. If the ball is batted or otherwise not controlled by an eligible offensive receiver in compliance with these criteria—such as when a receiver bobbles the ball and it falls to the ground—the play ends without further advancement. An incomplete pass also occurs if the ball strikes the ground or exits the field of play untouched by an eligible player, and in such cases, the game clock stops, providing a strategic tool for offenses to manage time in critical situations like the final minutes of a half or game. Strategically, incomplete passes are a double-edged sword: while they prevent positive yardage and risk penalties for if thrown away to avoid a , they are often employed deliberately near the sideline to halt the clock without turning the ball over, preserving opportunities for subsequent plays. The defines an incomplete pass as described above, with similar basic rules in and , though details such as catch criteria and enforcement, including instant replay reviews to distinguish between incompletions, fumbles, or completed catches, may vary by league.

Definition and Fundamentals

Definition

In , an incomplete pass occurs when a legal touches the ground or goes out of bounds before being secured by an eligible offensive , immediately ending the play. The itself must be thrown from behind the by the or another player in possession, with the ball initially moving toward the opponent's goal line after leaving the passer's hand. Upon an incomplete pass, the offensive team loses the down, and the ball is returned to the previous spot—typically the —with no advancement in yardage unless a penalty intervenes. The game clock stops in most cases, providing a strategic pause that can aid in time management. The concept of the incomplete pass evolved alongside the forward pass, which was legalized in 1906 to counteract the game's increasing lethality and stagnation after 19 player deaths the prior year, though early restrictions prohibited passes from being thrown or caught within five yards of the and made incompletes rare. Initially, incomplete passes carried harsh penalties, such as 15-yard losses or even turnover of possession, but rules gradually liberalized; by 1933, the permitted passes from anywhere behind the line, boosting aerial strategies and normalizing incompletes as a routine outcome.

Distinction from Complete Passes

A forward pass is considered complete in the when the intended receiver, while inbounds, secures firm control of the ball in their hands or arms before it touches the ground, touches the ground inbounds with both feet or any body part other than the hands, and performs an act common to the game—such as tucking the ball away, taking a step, or turning upfield—or maintains control long enough to enable such an act. This process must be fully executed without the ball touching the ground or being lost during the catch, distinguishing it from an incomplete pass where possession is not secured or maintained through these requirements. A historical nuance in ruling passes arose from the "tuck rule," applied until its repeal in , which treated a quarterback's incomplete forward passing motion as an ongoing pass even if the ball began to be tucked away. In the 2001 AFC Divisional playoff game between the and , this rule led officials to overturn an apparent fumble by quarterback —knocked loose by defender —ruling it an incomplete pass instead, as his arm was still moving forward when contact occurred. This preserved the down for the offense and underscored how subtle judgments on passing intent can alter outcomes between incomplete passes and fumbles. Strategically, incomplete passes interrupt offensive drives by halting the game clock without advancing the ball, often resulting in third-down situations or forcing punts, which can cede field position and scoring opportunities to the . In contrast, complete passes sustain , enabling first-down chains and positioning the offense closer to the end zone while building on prior gains. Incomplete passes also carry statistical repercussions in evaluating performance, particularly in the formula, which assesses efficiency across completions, yards, touchdowns, and interceptions relative to attempts. The formula—[(((Completions/Attempts - 0.3) × 5) + ((Yards/Attempts - 3) × 0.25) + (Touchdowns/Attempts × 20) + 2.375 - (Interceptions/Attempts × 25)) / 6] × 100—penalizes incompletions by inflating the denominator (attempts) without adding positive contributions to completions, yards, or touchdowns, thus reducing the overall and highlighting passing inefficiency.

Types of Incomplete Passes

Unintentional Incomplete Passes

Unintentional incomplete passes occur when a fails to result in a due to errors in execution rather than strategic design, primarily stemming from receiver drops, defender deflections, throws affected by , or inherent inaccuracies in aiming. Receiver drops happen when a targeted player fails to secure a catchable ball, often on passes deemed accurately thrown; league-wide, drop rates typically hover around 4-5% of catchable targets, with data showing variance based on receiver skill and target difficulty. Defender deflections, recorded as pass breakups, involve defensive players tipping or batting the ball to prevent . from rushing defenders disrupts , leading to hurried or off-target throws; studies indicate that under pressure, rates drop by 15-20% compared to clean pockets, as pressure forces quicker decisions and reduced accuracy. Inaccurate aiming by the , independent of , arises from misreads or mechanical flaws, accounting for a portion of the remaining incompletions in advanced metrics like adjusted percentage. These passes trigger an automatic stoppage of play, with the ball spotted back at the and the down counted, per NFL Rule 8, Section 1, Article 4, effectively ending the play immediately and stopping the game clock to reset the offense. This mechanic influences fourth-down decisions, as an unintentional incompletion on fourth down results in without a option, potentially shifting field position dramatically. In timed situations near the end of halves or games, the clock stoppage aids the offense in managing time, preserving opportunities for subsequent plays without bleeding seconds, unlike running plays that continue the clock. A notable historical example is in 2011, where the ' receivers contributed to several unintentional incompletions through drops, including instances by and others that stalled drives despite accurate throws from , ultimately factoring into the game's close 31-25 victory over the . Such errors highlighted how drops can alter momentum in high-stakes scenarios. Statistically, league-wide pass completion percentages have averaged 64-65% throughout the 2020s, with unintentional factors like drops, deflections, and pressure-induced inaccuracies driving much of the 35-36% incompletion rate and creating variance across teams and seasons, as tracked in Pro-Football-Reference league averages (e.g., 65.2% in 2020, 65.3% in 2024). This contrasts briefly with intentional incomplete passes, which are purposeful to avoid negative outcomes like sacks.

Intentional Incomplete Passes

Intentional incomplete passes in are deliberate actions by the to throw the ball in a manner that results in an incompletion, primarily to manage or avoid negative plays. The most common form is spiking the ball, where the immediately throws the ball into the ground after receiving the , stopping the clock without advancing the ball or losing yardage. This tactic is a key element of the , allowing teams to preserve precious seconds in critical situations, such as trailing late in a half. Unlike unintentional incomplete passes, which occur due to defensive pressure or execution errors, intentional ones are strategic tools designed to control the game's tempo. Strategically, spiking serves dual purposes: stopping the clock during no-huddle sequences and preventing a that could cost yardage or a potential . In the two-minute drill, for instance, quarterbacks use it when no timeouts remain, enabling the offense to quickly reset and attempt another play without the clock running. Another application involves "dumping" the ball short to an area unlikely to be caught, though this risks penalties if not executed as a legal spike; such moves are often employed under duress to evade tacklers while maintaining down and relative to a . These plays prioritize clock conservation and field position stability over gaining yards. Rule limitations strictly govern these actions to prevent abuse. Spiking is permitted only with immediate, continuous throwing motion after the snap and solely when the clock is running; any delay for strategic purposes renders it illegal, resulting in an intentional grounding penalty. This exception applies particularly in end-of-half or two-minute warning scenarios, where time management is paramount, but overuse is inherently limited by the cost of a down per attempt. In the 1980s, adaptations in the West Coast offense under coaches like Bill Walsh incorporated quick, rhythm-based passes that occasionally resulted in intentional-like incompletions to sustain offensive flow and avoid disruptions, influencing modern hurry-up strategies. If executed legitimately, intentional incomplete passes incur no penalty beyond counting as a down, allowing teams to manipulate game tempo effectively without field position loss. However, they do not advance the ball, forcing offenses to balance urgency with available downs, often leading to high-stakes decisions in close contests.

Pass Interference

Pass interference is a penalty in that occurs when a player makes illegal contact with an opponent in a way that significantly hinders an eligible receiver's opportunity to catch a forward pass, frequently resulting in an incomplete pass. This infraction applies only after a forward pass is thrown from behind the and before the ball is touched, and it targets actions more than one yard beyond the . Defensive pass interference (DPI) involves a illegally impeding a , such as by grabbing the jersey, hooking an arm, or playing through the receiver's back to disrupt the catch. Offensive pass interference (OPI), less commonly called, occurs when an offensive player, such as a blocker or ineligible receiver, impedes a 's ability to defend the pass, often through early downfield blocking before the pass is released. Incidental contact while both players are legitimately attempting to catch the pass does not constitute interference, nor does inadvertent tangling of feet if unintentional. The penalty for defensive pass interference is enforced from the spot of the infraction, awarding the offense an automatic first down and the yardage to that spot. If the foul happens in the end zone, it results in a for the offense. For offensive pass interference, the penalty is a 10-yard loss from the previous spot ( or end of the previous run), with no automatic first down. Key rules exempt pass interference if the forward pass is clearly uncatchable, such as when it is intercepted, lands , or is thrown too far beyond the receiver's reach to be reasonably caught. A notable case illustrating the impact of pass interference non-calls occurred in the between the and , where officials did not flag clear defensive interference on a third-down pass to wide receiver , resulting in an incomplete pass and preventing a potential that could have altered the game's outcome and led to a one-year trial of pass interference replay reviews in the 2019 season.

Intentional Grounding

Intentional grounding is a foul in when a passer, facing imminent loss of yardage due to defensive pressure, intentionally throws a without a realistic chance of completion to an , typically to avoid a . This infraction occurs beyond the in the field of play or and is distinct from legal incomplete passes, as it prioritizes evasion over genuine play development. The penalty for intentional grounding is enforced as a loss of down and 10 yards from the spot of the foul. If committed in the offensive team's , it results in a , awarding two points to the and possession to the offense via . Exceptions to the include situations where an eligible offensive is in the area of the intended pass, providing a realistic opportunity for . Additionally, no penalty applies if the has moved outside the —defined by the area between the outside edges of the offensive tackles—and throws the ball beyond the . In a 2024 rulebook clarification, the expanded this exception to apply when any portion of the 's body or the ball extends outside the , broadening protections for scrambling quarterbacks. The rule originated in the early to curb deliberate ball dumps for , with an initial 10-yard penalty introduced in 1914 under rules. In the , it was formalized during the , mandating a realistic completion chance to an and prohibiting "dumping" passes to the ground solely to evade tackles.

Special Cases and Variations

Backward Passes and Laterals

In , a , also known as a backward pass, is defined as a throw by a player that travels parallel to the or backward relative to the direction of play, exempt from the restrictions governing forward passes such as the single-pass limit per down or the requirement to originate from behind the . Unlike forward passes, which are ruled incomplete if not caught and result in a with the down ending, a lateral that is dropped or touches the ground is treated as a , becoming a live ball that neither team controls until recovered. This distinction means there is no "incomplete" designation for laterals; instead, the ball remains in play, allowing players from either team to advance it after recovery, potentially leading to significant gains or losses depending on who secures possession. Laterals are strategically employed in trick plays to deceive defenses and create unexpected opportunities for big plays, often following an initial or handoff to exploit defensive overcommitment. For instance, the involves a receiving a handoff and immediately pitching the ball backward to the , who then attempts a deep while the defense is focused on stopping the run. A renowned example is the Music City Miracle on January 8, 2000, when fullback fielded the ensuing kickoff and handed it to , who lateraled across the field to , enabling a 75-yard return for a game-winning against the . These plays highlight the high-risk, high-reward nature of laterals, as they can reverse field position dramatically but carry the danger of mishandling. The outcomes of incomplete laterals contrast sharply with those of forward incompletions, as a recovered loose ball from a lateral can be advanced for positive yardage by the offense or even the defense if they gain , rather than simply resetting the down at the previous spot of the ball. This live-ball status encourages aggressive recovery attempts and can extend plays well beyond typical scenarios, though it also amplifies the potential for turnovers if the defense capitalizes on the fumble.

Potential for Turnovers

In American football, a fumble on a forward pass occurs only after a receiver has secured possession (completing the catch) and then loses control, resulting in a loose ball that either team may recover and advance until it becomes dead or goes out of bounds. Under NFL rules, secure possession requires control of the ball with hand(s) or arm(s), while inbounds, and an act common to the game (e.g., ability to perform a football move like extending for yardage); if a bobble occurs without establishing this before the ball touches the ground—especially under the "going to the ground" rule where control is lost upon ground contact without such an act—the pass is ruled incomplete, deadening the play immediately with no recovery opportunity. Such scenarios are common in high-pressure situations like Hail Mary attempts, where tipped passes in the end zone can remain live if airborne, creating chaotic opportunities that the defense can exploit for interceptions rather than loose balls from incomplete catches. Incomplete passes also carry significant interception risks, particularly when defenders catch deflected or tipped balls that were initially headed toward an offensive player. Under the NFL's "tipped pass" doctrine, the initial deflection does not end the play; the ball remains live, and the down continues until the ball is possessed, touches the ground, or goes out of bounds, enabling defenders to position themselves for interceptions on the loose or airborne ball. This rule transforms what might appear as a mere incompletion into a potential turnover, as the defense can legally intercept any forward pass in flight, regardless of the initial tip. A notable example of this dynamic occurred during the 2014 between the and , where Russell Wilson's underthrown pass in the fourth quarter was tipped and intercepted by Packers Morgan , temporarily shifting momentum and appearing to secure a Packers victory before Seattle's comeback. This play highlighted how a seemingly routine incomplete pass can rapidly evolve into a game-altering due to defensive on a deflected ball.

League-Specific Rules

NFL Regulations

In the NFL, an incomplete forward pass is defined under Rule 8, Section 4, Article 1 as occurring when the ball touches the ground or goes out of bounds without being caught by an eligible receiver, resulting in a loss of down and the ball returning to the previous spot of the ball. A legal forward pass must be thrown from behind the line of scrimmage, established as the vertical plane through the forward point of the ball at the snap, per Rule 8, Section 3, Article 1; any pass released with the passer or ball beyond this line is illegal. Upon an incomplete pass, the game clock stops immediately, as specified in Rule 4, Section 4, Article 4, Item f and Rule 7, Article 1g, and restarts on the next snap unless other clock rules apply. Enforcement of incomplete pass rulings involves the referee signaling by crossing their arms in front of the chest to indicate the pass was not completed, a standard mechanic used by covering officials. The also regulates post-play behavior under Rule 12, Section 3 for , which includes excessive celebrations or following an incomplete —such as defensive players mocking the offense after a forced incompletion—with violations resulting in 15-yard penalties and fines ranging from $5,000 to $25,000 depending on severity and repetition. Incomplete passes integrate into official statistics by counting as attempts in the formula, which penalizes high incompletion rates through the component—calculated as (completions/attempts - 0.3) × 5, capped between 0 and 2.375—contributing to the overall on a 0-158.3 scale alongside yards per attempt, , and interception avoidance. This metric influences evaluations for awards like , where low incompletion percentages (e.g., above 70% ) often correlate with higher ratings and stronger candidacy, as seen in recent winners prioritizing over volume.

NCAA and Other Leagues

In the NCAA, rules governing incomplete passes emphasize in hurry-up offenses, where quarterbacks can spike the ball immediately after receiving the snap to stop the clock without incurring an penalty, as this action is exempt under NCAA rules. This exemption facilitates rapid no-huddle sequences, differing from professional rules by allowing more frequent intentional incompletions to preserve time without yardage loss. Unlike the , where the clock runs continuously after first downs except in the final two minutes of halves, NCAA games stop the clock after every first down for chain resets, enabling offenses to maintain and potentially increase incomplete pass frequency through aggressive play-calling. NCAA rules also integrate the targeting penalty with pass coverage, prohibiting forcible contact to the head or neck of a defenseless receiver during plays, which can result in disqualification if it contributes to an ; this ties into enforcement by prioritizing player safety over play outcome. Additionally, the NCAA lacks an equivalent to the former "tuck rule," treating a quarterback's forward arm motion followed by a as an only if the throwing action is clearly initiated, otherwise ruling it a recoverable based on and mechanics. In the Canadian Football League (CFL), the wider field (65 yards compared to the NFL's 53⅓ yards) and three-down system encourage longer throws to exploit space, resulting in potentially higher incomplete pass rates on deep attempts—as quarterbacks attempt riskier passes to gain the necessary yardage. under NFHS rules, updated in 2022, allows intentional incompletions outside the tackle box if an is in the area, similar to rules, with penalties for violations enforced from the spot of the foul to deter improper clock manipulation. These variations influence college strategies, particularly in the 2020s rise of (RPO) offenses, where faster tempos and read-based decisions lead to more incomplete passes as teams prioritize quick releases over high completion percentages to sustain drives and exploit defensive alignments.
