American Football IFAF Approved Ruling 9-2-2:I-V

I. After the ball is ready for play, Team A goes into a formation with two players split wide on both sides of the snapper and two other Team A linemen adjacent to the snapper. No more
than four players are legally in the backfield. Team A sends in two substitutes, who take positions on the line of scrimmage adjacent to the two split offensive linemen on the opposite side of the field of play from their team bench. This leaves Team A with nine players on the line of scrimmage and four backfield players all legally in position.
Immediately and before the snap, two Team A linemen nearest their team’s bench leave the field and are off at the snap. Seven players are on the line of scrimmage, five of whom are Team A linemen numbered 50 to 79. RULING: Penalty — 15 yards from the previous spot. This is a simulated replacement of a player to confuse the opponents. [Cited by 9-2-2-b]
II. On fourth down at Team B’s 12-yard line, A1 enters the field with a kicking shoe while his 11 teammates are in the huddle. A1 kneels and measures the distance from the neutral zone to the kicking spot. While his teammates are leaving the huddle, A1 leaves the field with the shoe. Team A quickly runs a play from scrimmage. RULING: Team A foul for unsportsmanlike conduct. Penalty — 15 yards from the previous spot. There shall be no simulated replacement of a player to confuse the opponents, and a player who communicates must remain in the game for one down. [Cited by 9-2-2-b]
III. A1 leaves the field of play during a down. Team A huddles with 10 players. Substitute A12 enters and A2 simulates leaving the field, but sets near the sideline for a “hide-out” pass. RULING: Penalty — 15 yards from the previous spot. This is a simulated replacement of a player to confuse opponents. [Cited by 9-2-2-b]
IV. While a team is legally set to attempt a field goal, the potential holder for the kick goes toward his team area asking for a shoe. A shoe is thrown on the field and the player, in motion toward his team area, turns toward the goal line. The ball is snapped to the player in the kicking position, who throws a pass to the player who had turned upfield after asking for a shoe. RULING: Penalty — 15 yards from the previous spot. [Cited by 9-2-2-b]
V. Team A is lined up in scrimmage kick formation and has been set for one second. One of the offensive backs shouts to and motions to A40, the blocker on the right wing, to get off the field. At the snap, A40 is in legal motion toward his sideline. A40 turns downfield and becomes a pass receiver. RULING: Penalty — 15 yards from the previous spot. This is a tactic associated with the substitution process to deceive opponents. [Cited by 9-2-2-b]
