What Is Pass Interference in Football? NFL Rules Explained

Pass interference is called when a player significantly hinders an eligible opponent’s chance to catch a forward pass more than one yard beyond the line of scrimmage. It can be committed by the defense or the offense, and ordinary contact is not automatically a foul.

Quick answer: Defensive pass interference usually involves a defender restricting a receiver while the ball is in the air. Offensive pass interference usually involves a receiver pushing off, blocking downfield, or illegally creating separation. The key questions are timing, location, material restriction, and whether the player is making a legitimate play on the ball.

This guide explains the current NFL rule, the difference between defensive and offensive pass interference, what does not count, the penalties, and the clues that help fans judge a close play.

What is pass interference in football?

Under Rule 8, Section 5 of the 2026 NFL Rulebook, pass interference requires an act by either team more than one yard beyond the line of scrimmage that significantly hinders an eligible player’s opportunity to catch a forward pass. The pass must be thrown from behind the line of scrimmage.

That definition is narrower than the phrase no contact. Receivers and defenders are allowed to compete for the football. A collision can be legal when both players are making a genuine attempt to reach, catch, or bat the pass. The foul appears when one player materially restricts the other player’s opportunity without a protected football action.

When can defensive pass interference happen?

Defensive pass interference applies from the moment the quarterback releases the pass until the ball is touched. Contact before the throw cannot be defensive pass interference, although it may qualify as defensive holding or illegal contact.

Officials commonly look for actions such as grabbing or turning a receiver, hooking an arm, playing through the receiver’s back, cutting off the receiver’s path without playing the ball, or making early contact that prevents a fair attempt at the catch.

The pass must also be catchable. If the ball clearly could not have been caught, defensive pass interference should not be called even when prohibited contact occurs.

What counts as defensive pass interference?

  • A defender grabs a receiver and restricts the route while the pass is in the air.

  • A defender hooks or pins an arm before the receiver can play the ball.

  • A defender makes early contact through the receiver’s body before the ball arrives.

  • A defender cuts off the receiver’s path without making a legitimate attempt to play the ball.

  • A defender tackles, turns, or materially displaces the receiver before the pass is touched.

What does not count as pass interference?

  • Incidental contact while both players make a genuine attempt to catch or deflect the pass.

  • Contact at or within one yard beyond the line of scrimmage.

  • Legal contact before the quarterback releases the pass, although another foul may apply.

  • Contact after the football has been touched.

  • A defender occupying a legal position and playing the ball rather than restricting the receiver.

  • Contact on a pass that is clearly uncatchable.

Does a defender have to turn and look for the ball?

No. There is no automatic penalty simply because a defender never turns their head. Looking back helps show that the defender is playing the football, but the actual decision depends on whether the defender materially restricts the receiver.

A defender can face the receiver and avoid a flag if there is no significant restriction. A defender can also look back for the ball and still commit a foul by grabbing, hooking, or going through the receiver. Head position is evidence, not the rule itself.

What is offensive pass interference?

Offensive pass interference occurs when an eligible offensive player significantly hinders an eligible defender’s opportunity to play the ball. Unlike defensive pass interference, the offensive restrictions apply from the snap until the pass is touched.

The most familiar example is a receiver extending an arm and pushing a defender away to create separation. Other common examples include blocking more than one yard beyond the line before the pass is touched, running into a defender to free a teammate, or grabbing a defender to prevent an interception.

When is a pick play legal?

A pick concept becomes illegal when an offensive player initiates material contact beyond one yard and blocks or screens a defender before the pass is touched. A receiver may run a route through traffic, and teammates can force defenders to navigate around each other, but the offense cannot deliberately create separation through an illegal block.

The practical clue is intent plus contact. A clean crossing route that makes defenders communicate is legal. A receiver who drives into a defender to spring a teammate is vulnerable to an offensive pass interference flag.

What is the penalty for pass interference in the NFL?

Defensive pass interference is enforced at the spot of the foul and awards the offense an automatic first down. That makes it one of the most damaging penalties in football because a deep foul can move the ball many yards.

When defensive pass interference occurs in the end zone, the ball is commonly placed at the one yard line. Special enforcement details can change when the previous spot is already near the goal line.

Offensive pass interference costs the offense 10 yards from the previous spot. The down is replayed unless another enforcement rule changes the result.

Three practical examples

  1. A defender hits the receiver before the ball arrives and never plays the ball. If the contact materially prevents the catch, that is defensive pass interference.

  2. A receiver and defender both look for the ball, collide shoulder to shoulder, and the pass falls incomplete. Genuine simultaneous play on the ball can make the contact legal.

  3. A receiver extends both hands and pushes the cornerback away before making the catch. That separation can produce offensive pass interference.

Pass interference compared with related fouls

Defensive holding and illegal contact normally occur before the pass is thrown. Defensive pass interference occurs after the pass is thrown and before it is touched. Offensive pass interference can begin at the snap and continues until the pass is touched.

This timing distinction explains why the same grab can produce a different penalty depending on when the quarterback releases the ball. For a complete overview, see Football Nation’s

Frequently asked questions

Can pass interference happen behind the line of scrimmage?

No. Pass interference requires the act to occur more than one yard beyond the line of scrimmage. Other contact rules may apply behind or near the line.

Can pass interference be called if the ball is not catchable?

Defensive pass interference should not be called when the pass is clearly uncatchable. Officials judge whether the receiver had a realistic opportunity to reach the football without the illegal contact.

Is face guarding automatically pass interference?

No. A defender does not have to turn their head. The foul depends on material restriction, not head position alone.

Can a receiver commit pass interference?

Yes. Pushing off, illegal blocking, grabbing a defender, or creating separation through material contact can result in offensive pass interference.

Does touching the ball end pass interference restrictions?

Yes. Pass interference restrictions end when the pass is touched. Contact after that moment is judged under other rules.

Football Nation takeaway

Watch four things on every close pass play: when the ball leaves the quarterback’s hand, where the contact happens, whether the contact materially restricts an eligible player, and whether each player is genuinely playing the football. Contact alone is not pass interference. Restriction without a protected football action is the real warning sign.
