What is a red card given for?

A red card is issued for serious misconduct that warrants immediate expulsion from the match. This action is a disciplinary measure taken by the referee to ensure the safety and fairness of the game. Serious misconduct may include violent conduct, using foul or abusive language, or actions that dangerously endanger the safety of another player. If a player receives a red card, they must leave the field and cannot be replaced, which places their team at a numerical disadvantage for the remainder of the game.

While other infractions, such as time-wasting or minor fouls, may result in cautionary measures like yellow cards or verbal warnings, a red card signifies a severe breach of the rules that fundamentally undermines the spirit of the game.
