What are the NFL's pass interference rules? Here's how they could impact Chiefs vs. Eagles in Super Bowl LIX

Defensive pass interference is called when a player focuses on the receiver rather than attempting to play the ball. This occurs when the defender cuts off the receiver's path or faces them, extending their arms without trying to intercept or deflect the pass. 

Lastly, if a defensive player restricts the receiver's movement without making an effort to catch, intercept, or bat the ball, it may also be deemed defensive pass interference, regardless of whether the pass is catchable.

What is Offensive Pass Interference?

Offensive pass interference takes place when an offensive player engages in blocking downfield before the ball is touched, particularly when the pass has traveled beyond the line of scrimmage. 

It can also occur when an offensive player initiates contact with a defender in order to create separation while attempting to catch a pass.

What is the penalty for Pass Interference?

In the NFL, defensive pass interference is treated as a spot foul, which means the penalty is applied at the exact location where the interference occurred. This can lead to significant yardage gains for the offense, especially on long passes. 

If the foul takes place in the end zone, the ball is moved to the one-yard line, and the offense gets an automatic first down.

On the other hand, offensive pass interference incurs a 10-yard penalty from the line of scrimmage and does not grant an automatic first down.

What is the difference between Pass Interference and Illegal Contact?

Illegal contact and pass interference are separate penalties in football, each with its own criteria, consequences, and effects on the game. Illegal contact takes place before the ball is thrown and incurs a five-yard penalty along with an automatic first down. 

In contrast, pass interference occurs after the ball has been thrown and can lead to significant yardage gains for the offense because it is a spot foul penalty.
