Effective rules
Scope: NFL football, 2026 edition
Every ruling and example here applies the 2026 Official Playing Rules of the National Football League, chiefly Rules 3-12, 7-2, 7-3 and 15. References such as “7-2-1” mean Rule 7, Section 2, Article 1. Sources were checked on 20 September 2026.
This page covers NFL ball carriers, including players returning interceptions or recoveries. It does not apply the separate NCAA, high school, Canadian or flag football codes. Examples assume no penalty changes the result.
Down by contact
Which body parts make a runner down?
Under NFL 2026 Rule 7-2-1(a), a runner contacted by an opponent is down when a body part other than a hand, including the wrist, or a foot, including the ankle, touches the ground. A knee, shin, elbow, forearm, hip or back therefore qualifies. Planting a hand to regain balance does not by itself end the run.
The opponent does not have to remain attached until the runner lands. If a defender trips a runner who staggers and falls as part of that tackle, the separation between them does not make the fall untouched. Conversely, an earlier brush does not permanently prevent a runner from regaining balance and continuing.
A player already on the ground with possession can also be touched down. Rule 7-2-1(f) specifically ends the play if an opponent touches the ball held by a grounded runner. A forceful tackle is unnecessary.
Untouched falls
Can a player get up and keep running?
Yes, if the fall was accidental, no opponent has made the player down, and no other dead-ball rule applies. Under NFL 2026 Rule 7-2-1, a knee touching the turf is not a universal end to every run.
Example: a running back slips on a cut, briefly touches a knee down and immediately gets up without defensive contact. The run may continue. If a defender touches the runner while the knee is still down, the play ends there.
For a receiver falling while catching a pass, first establish whether there is a completed catch. Ground contact can affect that separate question under Rule 8-1-3. See NFL catch rules before treating a dropped pass as a fumble or assuming the receiver can advance.
Giving oneself up
Kneels, slides and dives need no tackle
NFL 2026 Rule 7-2-1(c) ends the play when a quarterback immediately kneels or simulates kneeling, on either side of the line of scrimmage. Rule 7-2-1(d) also covers a runner who goes down or kneels and clearly makes no immediate effort to advance.
The same article covers feet-first and headfirst slides or dives. The ball becomes dead when something other than a hand or foot touches the ground. A simulated slide or dive makes it dead when the runner begins to simulate that ground contact. These provisions apply to runners generally, not only quarterbacks.
Example: a runner intentionally dives toward the first-down line. The knee lands while the ball is still short, and the runner then slides across the line. That later slide adds no yardage, even without a defender's touch. The ball's location at the dead-ball instant controls.
Defenders must pull up when a slide or dive begins. The rule nevertheless distinguishes unavoidable contact by a defender already committed from prohibited head or neck contact and other unnecessary roughness; every collision is not automatically a foul.
Forward progress
A standing runner can already be down
NFL 2026 Rule 3-12-1 defines forward progress by where the runner's advance toward the opponent's goal ends. Rule 7-2-1(b) ends the down when the runner is held or otherwise restrained so that this progress stops. Being driven backward afterward does not take away the protected spot.
Officials judge the action, rather than count a fixed number of seconds or defenders. A runner still driving a moving pile forward is different from a runner held upright and being carried backward. First contact alone does not necessarily stop progress.
Example: on third-and-two from the offense's 30, the runner advances the ball to the 33 before defenders stop the run and drive the player back to the 31. The progress spot is the 33, enough for a first down. The final landing spot does not erase the gain.
Voluntary retreat
The farthest point is not always protected
The NFL 2026 forward-progress rule protects a runner against being forced backward after the advance ends. It does not bank every yard previously reached while a live run continues.
Example: a runner reaches the offense's 33, voluntarily reverses direction to avoid a defender and is tackled at the 29. With no earlier stopped-progress ruling, the runner does not receive the 33 merely for having been there. Choosing to retreat can lose yardage.
If a runner escapes contact before officials judge progress ended, play can continue. Once progress has ended under Rule 7-2-1(b), however, a later escape cannot restart that down. The practical question is whether the defense ended the advance or the runner was still making a live attempt to gain ground.
Spotting the ball
Watch the ball, not the knee
Under NFL 2026 Rule 7-3-3, yardage is measured using the forward part of the ball at the applicable dead-ball spot. The knee may establish when the runner becomes down, but the ball determines where to spot the play.
Example: a contacted runner's knee touches at the offense's 39 while the controlled ball extends to the 40. The spot uses the ball at the 40. Reaching it to the 41 after the knee lands gains nothing.
A first down depends on that spot reaching the line to gain, not on the helmet or shoulders crossing it. The downs and distance explainer explains how the resulting spot affects the next down.
Airborne catches
A receiver driven backward can keep the catch point
NFL 2026 Rule 7-3-3 has a specific provision for an airborne player who controls a pass, is driven backward by an opponent and then completes the catch or interception inbounds. Forward progress is awarded where the opponent first contacted the player after control was established in the air.
Example: a receiver controls a pass with the ball at the opponent's 20, is contacted there and driven back, then completes the catch inbounds at the 22. The progress award preserves the 20. Merely touching the pass there would not suffice: control and a completed catch remain necessary.
Loose balls
Was the play dead before the ball came out?
Under NFL 2026 Rules 7-2-1 and 8-7-3, losing possession after being down by contact or after progress has stopped is not a live fumble. Losing it before the play ends can be. A runner need not reach the turf for a later strip to be too late.
Example: defenders hold a runner upright, end the runner's progress and then pull the ball away. The strip does not create a turnover. If the ball instead comes loose during the still-live tackle, officials apply the fumble and recovery rules.
The whistle communicates the end of the play; a qualifying dead-ball event can precede its sound. “The ball came out before I heard the whistle” therefore does not settle the ruling. Equally, an upright runner is not automatically protected from every attempted strip: progress must actually have ended.
Replay limits
What can video change?
NFL 2026 Rule 15-3 permits review of down by contact and whether possession was lost before the runner was down, out of bounds or had given up. Rule 15-2 requires clear and obvious video evidence to change the ruling.
A stopped-progress ruling has a narrower fumble exception: Rule 15-3-2, Item 4 permits review of whether the ball came loose before or simultaneously with defensive contact. It is not a general invitation to count a later strip after a valid progress stoppage.
If replay changes a down ruling to a fumble, a clear recovery in the immediate continuing action can establish possession. The award is at the recovery spot; a defender's subsequent return is not credited under that correction (Rules 15-2-3 and 15-3-2).
The spot can also be reviewed in relation to the first-down line under Rule 15-3-7. A team's spot challenge succeeds only if the decision to award a new series changes, even if officials adjust the ball's position. See NFL replay and coach's challenge rules for who may initiate review and when.
