Unsporting behaviour, dissent and celebrations
Not every card is for a tackle. A large share of a match's cautions have to do with how players behave.
Most common reasons for a caution
- Unsporting behaviour: for example, feigning a foul or an injury, stopping a promising attack with a foul, or handling the ball to try to score.
- Dissent by word or action: protesting decisions in an obvious way.
- Persistent offences: there's no fixed number of fouls; accumulation and repetition count.
- Delaying the restart of play.
- Failing to respect the distance at a corner kick, free kick or throw-in.
- Entering or re-entering the field without the referee's permission, or deliberately leaving it without permission.
Celebrations
Celebrating a goal is allowed, but there are limits. A player is cautioned if they:
- Remove their shirt or cover their head with it.
- Cover their head or face with a mask or similar item.
- Climb a perimeter fence or approach the spectators in a way that causes safety issues.
- Make provocative, derisory or inflammatory gestures.
Leaving the field to celebrate is not, on its own, a reason for a card, but the player must return as soon as possible.
Offensive language
Using offensive, insulting or abusive language or gestures isn't a yellow card: it's a sending-off. If play is stopped only for that offence, it restarts with an indirect free kick.
Practical tip
Managing behaviour doesn't always require a card. A timely warning, a word with the captain or a close presence prevent many situations. But when the conduct is clearly punishable, the card protects your authority for the rest of the match.
