What should a player do if they receive a second yellow card in a match?

When a player receives a second yellow card in a match, the appropriate action is to receive a red card and be sent off. This rule is in place to ensure fair play and is a critical aspect of maintaining discipline within the game. The first yellow card serves as a warning for misconduct, and if a player commits a second offense that warrants another yellow, it escalates to a red card. This results in the player being removed from the match, and they cannot be replaced, leaving their team with one fewer player for the remainder of the game. This automatic dismissal reinforces the importance of adhering to the rules and encourages players to play within the spirit of the game.
