If an offensive player unnecessarily delays putting the disc into play in violation of rule 20.B, a defender within ten feet of the spot the disc is to be put into play may issue a delay of game warning instead of calling a violation, by announcing "delay of game" and counting down from three to zero at intervals of at least one second to provide an opportunity for the offensive player to react to the warning. Play then continues as follows:
If the behavior in violation of rule 20.B is stopped before the full utterance of the word "zero," the marker stops the count-down and may only initiate the stall count as usual, according to 15.A.2.
An example of "stopping" behavior in violation of rule 20.B is to begin moving toward the disc at walking pace. Another example would be to run downfield, leaving the disc for someone else to pick up. However, if a player is taking more time than reasonably necessary to put the disc into play by standing back from the disc, wandering around near the disc, or standing over the disc, continuing such behavior during the three-second countdown will allow a marker to initiate the stall count under 14.A.5.
