Both teams may substitute after a goal is made or if there is an injury. The defender must be at least one disc length away from the offensive player, and the distance from the next defender should be at least 10 feet. Picks are illegal. Interceptions in your own goal must be thrown back out. If a strip does occur, however, the disc will be returned to the thrower and play will continue.
Fouls consist of any contact made with a player.
A person who is fouled should call the foul. If no foul is called, play continues. When a foul is committed by a defensive player play stops and possession reverts back to the thrower. In the event of a time game at the end of regulation, play will continue until the next goal is scored.
