It is the mutual responsibility of both players to respect each other's position and not infringe into this area once it is established. The Receiver 15.1. The receiver is any offensive player either in the act of catching the disc, or not in possession of the disc. After catching a pass, the receiver is only allowed the fewest number of steps required to stopping and establishing a pivot foot. If the disc is caught simultaneously by offensive and defensive players, the offense retains possession.
Fouls are the result of physical contact between opposing players.
The player initiating contact is guilty of a foul. A throwing foul may be called when there is contact between the thrower and the marker. Contact after the disc has been released is not sufficient grounds for a foul, but should still be avoided whenever possible. When a thrower or the marker commits a foul, play stops and possession reverts back to the thrower after a check. If the thrower is fouled in the act of throwing and the pass is completed, the foul is automatically declined and play continues without interruption.
