Which situation allows a player to remain on the field after receiving treatment for an injury?

The situation where a player is allowed to remain on the field after receiving treatment for an injury is when the player has received quick treatment for an injury caused by a yellow card or red card offense. In accordance with the Laws of the Game, when a player sustains an injury as a direct result of a foul that leads to a yellow or red card being issued, the player can receive treatment on the field, often because the game is temporarily halted for the disciplinary action. This allows for a quicker recovery process in the context of the match.

Other scenarios, such as receiving treatment for any injury or expressing a willingness to play despite a minor injury, do not provide the same allowances. Players typically need to leave the field for treatment of non-foul-related injuries or when a significant amount of time is needed to address the injury. The rule is meant to ensure that the game maintains its flow and competitiveness, while providing safety measures for players when directly affected by the actions of an opponent.
