• the referee cautions him for unsporting behaviour and orders him to leave the field of play
• if the referee has stopped play, it is restarted with an indirect free kick for the opposing team from the position of the ball at the time of the stoppage (see Law 13 - Position of free kick)

If a player changes places with the goalkeeper without the referee's permission before the change is made:

• the referee allows play to continue
• the referee cautions the players concerned when the ball is next out of play

In the event of any other infringements of this Law:

• the players concerned are cautioned
• the match is restarted with an indirect free kick, to be taken by a player of the opposing team from the position of the ball at the time of the stoppage (see Law 13 - Position of free kick)
