If the disc is out-of-bounds (10.E) or comes to rest in the end zone, a member of the team becoming offense must put the disc into play within twenty seconds after it comes to rest.
If the disc is in the end zone, after twenty seconds elapse, a defensive player within 10 feet of the disc may announce disc in, and then initiate and continue the stall count, but only if a defensive player has given audible warnings of twenty, ten and five seconds (the pre-stall).
If the disc goes out of bounds, grab another game disc to minimize delay.
