American Football Rules IFAF Approved Ruling 8-6-1:I-III

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) [Cited by 8-6-1-a]
