Only ONE player may guard the person in possession of the disc. If the disc is dropped by the thrower without interference by a defender, a turnover results. If the disc is simultaneously caught, offense retains possession. A rolling or sliding disc may be stopped by any player, but may not be advanced in any direction. After the disc is stopped, no defensive player may touch it.
Possession is gained at the point where the disc is stopped.
Any member of the team gaining possession of the disc may throw it. Bobbling to gain control is permitted, but tipping to oneself is not allowed. Any physical contact during the throw is a foul against the defender. The thrower may not push the player defending. If the pass is completed, the foul is automatically declined and play proceeds without stopping.
