Item 1. Down by Contact. Whether a player was down by contact while in possession of the ball.
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 an incomplete pass out of bounds.
A player is in possession when he is inbounds and has control of the ball with his hands or arms.
To gain possession of a loose ball that has been caught, intercepted, or recovered, a player (a) must have complete control of the ball with his hands or arms and (b) have both feet or any other part of his body, other than his hands, completely on the ground inbounds, and, after (a) and (b) have been fulfilled, perform any act common to the game (e.g., tuck the ball away, extend it forward, take an additional step, turn upfield, or avoid or ward off an opponent). It is not necessary that he commit such an act, provided that he maintains control of the ball long enough to do so. This rule applies in the field of play, at the sideline, and in the end zone.
Notes:
If a player who has completed the first two, but not the third requirement for possession, contacts the ground and loses control of the ball, there is no possession if the ball hits the ground before he regains control, or if he regains control out of bounds. If a player would have caught, intercepted, or recovered a ball inbounds, but is carried out of bounds, player possession will be granted (8-1-3-Note 5).
Any forward pass (legal or illegal) is incomplete and the ball is dead immediately if the pass strikes the ground or goes out of bounds. An incomplete pass is a loss of down, and the ball returns to the previous spot.
Note: If there is any question whether a forward pass is complete, intercepted, or incomplete, it is to be ruled incomplete.
A catch is made when a player inbounds secures possession of a pass, kick, or fumble that is in flight. An interception is made when an opponent who is inbounds catches a forward or backward pass or a fumble that has not touched the ground.
