State of the disc: The nature of play at a particular moment during the game. There are three states of the disc:
A disc is "in play" when players are allowed to move and play may proceed without the defense's acknowledgment. An in-bounds disc in the central zone is in play. The disc is subject to a turnover. If no player has possession of a disc in play, any offensive player may become the thrower by taking possession of the disc (14.A). Once a player has possession of the disc, they must establish a pivot at the spot of the disc 14.A.2) prior to attempting a pass (17.K).
A disc is "live" when players are allowed to move and the disc is subject to a turnover, but the thrower cannot make a legal pass (e.g., walking the disc to the spot where it is to be put into play). For a live disc to be put into play, the thrower must (1) establish a pivot at the appropriate spot on the field, and (2) touch the disc to the ground (14.B).
A disc is "dead" when play has stopped and can continue only with a check (see 9.D). The disc is not subject to a turnover. A dead disc may change states to either live or in play after a check depending on the circumstances.
