Yellow and red cards are used in futsal. The yellow card is to caution players over their actions. If they get two, they are given a red card, which means they are sent off the field. A yellow card is shown if a player shows unsporting behaviour, dissent, persistent infringement of the Laws of the Game, delaying the restart of play, failing to respect the distance of the player from the ball when play is being restarted, infringement of substitution procedure or entering, re-entering and leaving the field without the referee's permission. A player is shown the red card and sent off if they engage in serious foul play, violent conduct, spitting at another person, or denying the opposing team a goal by handling the ball (except the goalkeeper inside their penalty area). Also punishable with a red card is denying an opponent moving towards the player's goal a goalscoring opportunity by committing an offence punishable by a free kick or a penalty kick and using offensive, insulting or abusive language or gestures. A player who has been sent off must leave the vicinity of the field.
