Ifab has not mandated the change for other competitions

Decision follows Prestianni and Afcon final controversies

Any player who covers their mouth when confronting an opponent or who leaves the pitch in protest at a refereeing decision could receive a straight red card at this summer’s World Cup.

In a regulation change approved by the International Football Association Board (Ifab) ahead of Thursday’s Fifa Congress in Vancouver it was confirmed that the new protocols will be in place for the tournament, which begins in June.

Ifab has not mandated that the rules be enforced in other competitions, and it will be left to other competitions’ organisers to decide whether to introduce them.
