There are many ways that a player can commit a foul. Players will not usually be booked for committing technical fouls as they are seen as minor offences. The third form of foul in Gaelic Games is called 'Dissent' . Dissent is to openly disagree with any official about any decision. Unlike soccer, there are no yellow or red cards given by the referee for foul play.
Players simply have 'their name taken' .
This is known as being 'booked' . The referee makes a written note of this in his pocket book. If a player has to be booked twice, he is 'sent off' . The referee will point in the direction of the sideline and the player will leave the pitch. The referee's gesture of pointing to the sideline is to allow the crowd to understand his decision.
