The ruling on the field is pass interference.
It is pass interference by either team when any act by a player more than one yard beyond the line of scrimmage significantly hinders an eligible player’s opportunity to catch the ball. Pass interference can only occur when a forward pass is thrown from behind the line of scrimmage, regardless of whether the pass is legal or illegal, or whether it crosses the line.
Defensive pass interference rules apply from the time the ball is thrown until the ball is touched.
The ruling on the field is a touchdown.
It is a Touchdown if any part of the ball is on, above, or behind the opponent’s goal line while legally in possession of an inbounds player, provided it is not a touchback.
The ruling on the field is incomplete pass.
An official shall declare the ball dead and the down ended when a runner is contacted by an opponent and touches the ground with any part of his body other than his hands or feet. The ball is dead the instant the runner touches the ground. A runner touching the ground with his hands or feet while in the grasp of an opponent may continue to advance; or if, after contact by an opponent, any part of a runner’s leg above the ankle or any part of his arm above the wrist touches the ground, the runner is down.
