Key Responsibilities

Critical duties clock operators must follow to run a fair, accurate game.

Game Clock Operators

• Start the clock on the referee's signal after the ready-for-play whistle.
• Stop the clock immediately when the referee signals a dead ball or timeout.
• Keep the correct time during overtime and ensure the clock is accurate and synchronized.
• Never start or stop the clock on your own judgment — always follow the referee's signal.

Play Clock Operators

• Start the play clock on the referee's ready-for-play signal.
• Enforce the 40-second play clock by default; 25 seconds after a timeout or change of possession.
• Signal when two seconds remain so officials can watch for a snap before expiry.
• Reset the play clock if the play clock is stopped or never started by rule.
