Rules Analysis
If the disc comes to rest other than on the playing field proper, 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 not reasonably retrievable within twenty seconds (e.g., far out-of-bounds or through a crowd), the player retrieving it may request another disc and any delay or pre-stall count is suspended until the offensive player receives the new disc.
If the disc is in the end zone, after twenty seconds elapse, a defensive player within three meters 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 is out-of-bounds, after twenty seconds elapse, a defensive player within three meters of the spot the disc is to be put into play 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 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.
For an out-of bounds disc that has come to rest on the central zone, the team becoming offense will have twenty seconds to put it into play.
