Can a Receiver Push a Cornerback?

Both college and the NFL also have offensive pass interference rules. At both levels, the offense can't block the defense beyond the line of scrimmage while the ball's in the air. Receivers aren't allowed to push off defenders.

When can a cornerback touch a receiver?

The 5-yard contact rule in the NFL allows defensive backs to make contact with wide receivers at or less than 5 yards. Anything over 5 yards will result in an illegal contact penalty.

Is push off legal in football?

Although pushing is permitted, illegal contact is not permitted during games. Illegal contact occurs when a player is still making significant contact with a receiver after the receiver crosses five yards over the line of scrimmage. The official will call a penalty if this occurs.
