Approved Rulings 7-1-4:IV-VI

IV. Team A, with fourth and eight, sends two substitutes numbered 21 and 33 into the game as exceptions to the mandatory numbering, and they are positioned legally on their line of scrimmage between the end players on the line of scrimmage. After the ball is snapped, a Team A player, 15 yards deep in a scrimmage kick formation, throws a legal forward pass to an eligible receiver for a 10-yard gain. RULING: Legal play (Note: The same play from a field goal formation is legal). [Cited by 1-1-1-b-2]

V. A33, an exception to the mandatory numbering rule, assumes a position on the line of scrimmage next to end A88. Before the snap, A88 moves to a backfield position and the flanker on the opposite side of the line moves to an end position on the line. RULING: Illegal formation. Since A33 is now an end, he is thus in an illegal position at the snap
(live-ball foul). Penalty — five yards from the previous spot. [Cited by 1-1-1-b-2]

VI. A33, an exception to the mandatory numbering rule, assumes a position on the line of scrimmage to the left of snapper A85, who is on the end of the line. All other Team A players on the line are to A33’s left. After a one-second stop, all players on the line except A85 legally shift to the other side of the ball, with A33 now positioned as an end. RULING: If the ball is snapped with A33 in this position, it is a foul for an illegal formation. A33 may not legally be on the end of the line at the snap. Penalty — five yards from the previous spot. [Cited by 1-1-1-b-2]
