What should happen if a player is cautioned for illegal equipment during the game?

When a player is cautioned for illegal equipment during a game, the appropriate action is for the player to change the offending equipment but remain on the field of play. This means that the player does not need to leave the pitch entirely, which allows for the continuity of the game without a substitution being necessary. The caution serves as a reminder for the player to comply with the equipment rules, ensuring safety and fairness within the game.

Cautioning a player in this context is about ensuring compliance, not penalizing the team with severe repercussions like removing the player from the game or awarding the opposing team a penalty kick or free kick, which would disrupt the flow of the match significantly. It highlights the importance of maintaining the integrity of play while also upholding the regulations regarding players' equipment.
