(1) “If a runner (including a quarterback) gives himself up, then he is down where the first body part touches the ground. The runner should not benefit from additional yardage after the first body part touches. Defenders do not have to go down to initiate contact to stop a runner from gaining more yards after he contacts the ground.”
(2) “Quarterbacks and all runners should be reminded that they must give themselves up early, and that if a defender has committed to a tackle, contact may occur. However, that contact cannot be late or to the head or neck area of the player who gave himself up.”
(3) “A quarterback does not have to slide feet first to be considered to be giving himself up. Regardless whether the slide is feet first or head first, as long as he gives himself up, he should receive the protections afforded to him as a player in a defenceless posture.”
