3rd down ends short of the line to gain. Team A sends in 4 substitutes and 5 players begin to leave the field for a field goal attempt. A12, the quarterback, who participated in the previous play stops and sets up on the line of scrimmage very close to the sideline. After the ball is snapped, the holder A18 throws a pass to A12 who catches the ball and scores a touchdown.
Am I wrong on this? A12 is charged with an UNS and if that is his second one of the game he is DQ'd. The rule book even states that flagrant offenders will be disqualified for this foul under 9-2-2-b.
