Infringements
If a player moves from their required position as detailed above, or if the ball is not kicked forward, the kick is retaken. Failure to maintain position may constitute misconduct and be punished by a caution (yellow card).
It is an offence for the kicker to touch the ball a second time until it has been touched by another player; this is punishable by an indirect free kick to the defending team from where the offence occurred, unless the second touch was also a more serious handling offence, in which case it is punishable by a direct free kick or penalty kick, as appropriate.
