American Football NCAA Approved Ruling 9-1-7
I. After the ball is dead, a player throws himself onto an opponent lying on the ground. RULING: Personal foul. Penalty—15 yards from the succeeding spot and first down if by a Team B player and not in conflict with other rules. “Piling on’’ applies to a ball carrier or to any other opponent who is prostrate when the ball becomes dead.
II. On a sweep play toward the sideline, linebacker B55 goes out of bounds to avoid a block. Guard A66 is leading the play, and just as he steps on the sideline with his front foot he drives his shoulder in the waist at the front of B55 who is still out of bounds. RULING: Legal block. A66 does not have both feet out of bounds.
