Pass interference requires significant hindrance, not merely contact.

The governing rule used on this page

The primary scope is the 2026 Official Playing Rules of the National Football League, effective for the 2026 NFL preseason, regular season and postseason. The controlling provisions are Rule 8, Sections 4–6, with replay consequences in Rule 15.

An NCAA comparison appears below because its enforcement and qualifying pass are materially different. NFHS high-school, CFL, IFAF, youth and flag competitions use separate rules; this page does not treat the NFL test as universal.

Six questions decide an NFL pass-interference call

1. Was a forward pass thrown from behind the line? NFL pass interference can apply even if that pass is otherwise illegal and even if it does not cross the line of scrimmage.
2. Was the act more than one yard beyond the line? At or within one yard, it is not pass interference, although holding or another foul may apply.
3. Was the affected opponent eligible? The rule protects an eligible player's opportunity to catch.
4. Was the act inside the correct time window? DPI begins when the pass is thrown; OPI begins at the snap. Both windows end when the ball is touched.
5. Was there significant hindrance? Contact alone is not enough. The act must meaningfully restrict the catching opportunity.
6. Was the pass clearly uncatchable, or was the contact otherwise permissible? If so, there is normally no pass interference, subject to the offensive blocking exceptions in Rules 8-3-2 and 8-5-4.

What defenders may not do after the throw

NFL Rule 8-5-2 lists acts that can be interference while the ball is in the air. The common thread is restriction, not how dramatic the collision looks. Examples include:

• Playing through an opponent's back to reach the ball.
• Grabbing an arm so the receiver cannot complete the catch attempt.
• Extending an arm across the receiver's body and restricting movement.
• Cutting off the receiver's path with contact while not playing the ball.
• Hooking the receiver and turning the receiver's body before the ball arrives.
• Shoving to create separation from an opponent.

A defender can make legal contact while genuinely competing for the ball if the defender has position and does not significantly hinder the opponent by a prohibited act.

The offense has a longer restriction window

Offensive restrictions begin at the snap, not at the throw. Rule 8-5-4 makes it OPI for an offensive player to block more than one yard beyond the line clearly before the pass is thrown. It is also OPI to block beyond that line while the pass is airborne when the block is in the vicinity of the intended receiver. Rule 8-3 contains a narrow continuous-contact exception for an ineligible blocker engaged from within one yard.

A receiver's push-off can also be OPI under Rule 8-5-2 when it creates separation. Crossing routes and natural traffic are not automatically illegal “picks”: officials must identify a block, push or other significantly hindering act rather than infer a foul from the route design alone.

Before the throw, after a touch and near the line

• Defensive contact before the throw: it cannot be DPI because the defensive window has not opened. It may be defensive holding or illegal contact under Rules 8-4 and 12-1-6.
• Offensive contact before the throw: a downfield block can already be OPI because the offensive window opened at the snap.
• After any player touches the pass: pass-interference restrictions end. A later block may be legal, while holding, a personal foul or another independently illegal act can still be penalised.
• At or within one yard of the line: Rule 8-5-1 excludes the act from pass interference. That does not create a free-contact zone for every other rule.

Contact can occur without a foul

Rule 8-5-3 expressly permits incidental hand, arm or body contact when both players are competing for the ball or neither is looking for it. If there is doubt whether that contact was incidental, the NFL rule directs no interference. Inadvertent tangling of feet is also permissible in those circumstances.

A player may lay a hand on an opponent without restricting the opponent, and a player who has gained position may make contact while attempting to catch the ball. “Equal rights to the ball” does not excuse a hook, arm bar or shove; it protects a legal path and genuine attempt, not any contact made while looking back.

“Uncatchable” means clearly out of reach of the involved players

Contact that would otherwise be interference is permissible when the pass is clearly uncatchable by the involved players. A difficult throw, a receiver who probably would have dropped it or a ball requiring a demanding adjustment is not necessarily clearly uncatchable. Officials judge where the ball is going and whether the restricted player had a realistic opportunity without the interference.

The uncatchable-pass exception does not erase every foul. A facemask, unnecessary-roughness act or hold may stand on its own. It also does not excuse the offensive downfield-blocking acts covered by Rules 8-3-2 and 8-5-4.

A defender need not turn their head

The 2026 NFL rule does not make “failing to look back” a separate foul. A defender facing the receiver can avoid DPI if the contact is incidental and does not restrict, and Rule 8-5-3 even addresses incidental contact when neither player is looking for the ball.

Head position is evidence, not the legal test. A defender who never locates the pass may be more likely to cut off, play through or restrict the receiver, but officials still need the significantly hindering act. Conversely, looking for the ball does not legalise an arm grab or body-turning hook.

DPI is a spot foul; OPI is ten yards

Accepted NFL DPI gives the offense a first down at the spot of the foul. Accepted OPI is a loss of 10 yards from the previous spot. If the offense completes the pass despite DPI, it may decline the penalty and keep the play when that result is better.

If DPI is also a personal foul, Rule 8-5 permits the personal-foul penalty to be enforced as well. That is different from simply relabelling ordinary interference as a personal foul.

End-zone DPI does not award a touchdown

When the DPI spot is behind the defense's goal line and the previous spot was on or outside the 2-yard line, the NFL places the ball at the defense's 1-yard line and awards a first down. If the previous spot was inside the 2, the ball goes halfway to the goal line with a first down.

The receiver is therefore not credited with a catch or touchdown merely because the foul prevented a possible score. The penalty creates the specified next-down position.

The interference judgment itself is not reviewable

Under NFL Rule 15-4, illegal receiver contact and blocks are non-reviewable, and any aspect not listed as reviewable is also excluded. A coach cannot challenge an ordinary judgment that contact was or was not DPI or OPI.

Replay can still change an objective fact that is independently reviewable. Rule 15-3-3, for example, permits review of whether the pass was touched; a touching away from and noticeably before the contact removes a pass-interference foul. Rule 15-7 also permits correction of penalty administration, including yardage, the down, the fouling player's number and the spot of the foul. That is not a general replay review of interference.

A defender hooks the receiver 18 yards downfield

Situation: after a catchable pass is thrown, the defender hooks the receiver's near arm and turns the receiver before the ball arrives.

NFL 2026 ruling: DPI under Rule 8-5-2. The act occurred after the throw, more than one yard beyond the line and significantly restricted an eligible receiver. If accepted, the offense receives a first down at the foul spot.

Two players' feet tangle while tracking the pass

Situation: receiver and defender run side by side, their feet inadvertently tangle and both fall before a catchable pass arrives.

NFL 2026 ruling: no pass interference under Rule 8-5-3 if the tangling was inadvertent while both were playing the ball. The decisive fact is accidental entanglement rather than a trip, grab or path-cutting act.

A slot receiver blocks before a screen pass

Situation: before the quarterback releases a forward pass from behind the line, a slot receiver deliberately blocks a defender four yards downfield to clear space for the intended receiver.

NFL 2026 ruling: OPI under Rule 8-5-4. The pass need not cross the line; the decisive facts are the clear offensive block, its location more than one yard downfield and its timing before the throw. The accepted penalty is 10 yards from the previous spot.

A tip occurs before the contact

Situation: a lineman touches the pass, and only afterward a defender contacts the intended receiver downfield.

NFL 2026 ruling: the later contact is not pass interference because the PI window ended at the touch. If the touching ruling changes on replay, Rule 15 allows that objective fact to affect the foul. Any independently illegal holding or personal foul must still be analysed separately.

College football uses a different qualifying pass and DPI cap

NCAA Rule 7-3-8 applies pass-interference rules during a down in which a legal forward pass crosses the neutral zone, and physical contact is required. NCAA DPI is a spot foul with a first down when the foul is less than 15 yards beyond the previous spot; at 15 yards or more, enforcement is 15 yards from the previous spot with a first down. That cap is the major contrast with NFL spot enforcement.

For the 2026 NCAA season, the NCAA changed OPI from 15 yards to 10 yards from the previous spot. Matching ten-yard OPI penalties do not make the two codes identical: the qualifying-pass language, contact rules, DPI enforcement and replay framework still differ. Conferences may issue additional officiating guidance, but cannot be assumed to use the NFL rule.

Five shortcuts that produce the wrong ruling

• “Any early contact is DPI.” NFL DPI begins only when the pass is thrown; earlier defensive contact may be another foul.
• “Not looking back is automatic DPI.” The rule asks whether an act significantly hindered, not where the player's head was facing.
• “A tipped pass makes all later contact legal.” It ends PI restrictions, but other contact fouls remain possible.
• “Uncatchable erases a downfield pick.” The NFL rule preserves its offensive blocking provisions.
• “College uses the NFL spot foul.” NCAA DPI is capped at 15 yards from the previous spot.
