If the thrower has not released the disc at the first utterance of the word "ten," it is a turnover. The marker loudly announces "stall" and play stops. If the disc is thrown, play continues until the outcome of that pass is determined. A stall is not a violation and the Continuation Rule (17.C) does not apply.
If the stall is uncontested, the disc is returned to the thrower at the place of the stall. The thrower then places the disc on the ground and loudly announces "disc in" and the disc is in play.
