Referee
- Signals stoppage of play (whistle only if necessary)
- Points 45 degree upward toward the left (Referee's side) corner
- Ensures that the ball is properly placed within the corner arc
- Enforces the required distance if necessary
- Varies from the recommended position (see diagram) if needed to focus on potential conflicts among players to confront interference with the goalkeeper, or to prepare for an unusual team tactic on the restart (e.g., "short" corner kick)
Assistant Referee
- Moves to the near corner and takes position on the goal line behind the flag
- Signals only if referee makes eye contact to ask for assistance
- If the ball goes completely out of play and immediately returns to the field, signals with a vertical flag until acknowledged by the referee, then points flag 45 degrees downward toward the near corner
- Steps upfield from goal line to avoid pointing the flag off the field
- Following the kick, moves to the offside position as quickly as possible
