American Football NCAA Approved Ruling 8-6-1
I. Team A’s fumble strikes the pylon at the intersection of Team B’s goal line and sideline. RULING: Touchback. Team B’s ball at the 20-yard line (Rules 7-2-4-c and 4-2-3-b).
II. B1 intercepts Team A’s legal forward pass in his own end zone, after which A1 snatches the ball from his hand while in Team B’s end zone. RULING: Touchdown. The ball is not automatically dead when intercepted, but it becomes dead when A1 gets possession. However, if in the judgment of the official there is perceptible time during which the Team B player made no attempt to advance after the interception, declaring a touchback is justified.
III. Third and five at the B-20. Defensive back B44 intercepts a forward pass in his end zone. While still in the end zone he fumbles the ball. It rolls forward, goes into the field of play, and in the scramble A33 kicks the ball into the end zone and over the end line. RULING: First and 10 for Team B at the B-30. The result of the play is a touchback, and therefore the basic spot for enforcement of the 10-yard penalty for illegally kicking the ball is the B-20. The touchback results because of the new impetus given by A33 kicking the ball. (Rules 2-16-1-a, 8-7-1, 10-2-2-d-2(a))
