What action results in an automatic red card?

The action that results in an automatic red card is violent conduct. This type of conduct is defined as any physical act against an opponent or an official that is deemed to be excessively aggressive or reckless. Violent conduct can include actions such as punching, kicking, or using excessive force in a challenge, even if the act does not connect with an opponent. Referees are instructed to take a strong stance against such behavior to ensure the safety of all players on the field.

In this context, while dissent towards the referee, foul play, and diving can result in other disciplinary actions, they do not carry the same immediate consequences as violent conduct. Dissent may lead to a yellow card, foul play can result in free kicks or yellow cards depending on the severity, and diving (attempting to deceive the referee) also typically results in a caution. However, violent conduct unequivocally warrants a red card for its serious implications on player safety and the integrity of the game.
