When will the Red card be shown by referee?

Answer 1

The red card is shown by the referee to indicate that a player has been sent off or expelled from the game for a serious misconduct or violation of the rules. It is typically shown when a player has committed a violent or dangerous foul, denied a clear goal-scoring opportunity by fouling an opponent, used abusive or offensive language, or received two yellow cards in a single match. The decision to show a red card is at the discretion of the referee based on their judgment of the severity of the offense.
