What is the proper procedure if a player is given a red card?

When a player is issued a red card, the proper procedure is for the player to leave the field immediately and not be replaced. This action signifies that the player has committed a serious foul or misconduct that warrants expulsion from the match. The team must continue with one less player, which can impact the dynamics of the game.

In this context, the other options do not reflect the standard rules regarding red card offenses. A temporary suspension does not align with the protocol for a red card, as such a card indicates a permanent dismissal from the match. Similarly, allowing a player to return after a specific period like five minutes or permitting a replacement would undermine the severity of the misconduct associated with the red card. Thus, it's essential to adhere strictly to the rule that prohibits replacement after a red card has been issued.
