<P> The referee may consider serious and / or persistent offences to be misconduct worthy of an official caution or dismissal from the game . Association football was the first sport to use coloured cards to indicate these actions . </P> <P> A yellow card is shown by the referee to indicate that a player has been officially cautioned . The player's details are then recorded by the referee in a small notebook; hence a caution is also known as a "booking". A player who has been cautioned may continue playing in the game; however, a player who receives a second caution in a match is sent off (shown the yellow card again, and then a red card). Law 12 of the Laws of the Game (which are set by the International Football Association Board and used by FIFA) lists the types of offences and misconduct that may result in a caution . It also states that "only a player, substitute or substituted player" can be cautioned . A player is cautioned and shown a yellow card if he / she commits any of the following offences: </P> <Ol> <Li> Unsporting behaviour </Li> <Li> Dissent by word or action </Li> <Li> Persistent infringement of the Laws of the Game </Li> <Li> Delaying the restart of play </Li> <Li> Failure to respect the required distance when play is restarted with a corner kick, throw - in or free kick </Li> <Li> Entering or re-entering the field of play without the referee's permission </Li> <Li> Deliberately leaving the field of play without the referee's permission </Li> </Ol> <Li> Dissent by word or action </Li>
