Is it true that the referee does not need to stop play for an outside agent on the field?

The assertion that the referee does not need to stop play for an outside agent on the field is false. According to the Laws of the Game, if an outside agent—such as a spectator or team personnel—enters the field of play and potentially affects the game, the referee is obligated to stop the match. This action is taken to ensure the safety of players and the integrity of the match.

Stopping play allows the referee to address the situation appropriately, whether it involves clearing the outside agent from the field or managing any disturbance caused. It is crucial for maintaining order and ensuring a fair environment for the players and the ongoing match. Therefore, any interaction or interference by an external party necessitates the game's suspension until the matter is resolved.
