World Cupplayers who cover their mouths during confrontations with opponents will face a red card as part of a new initiative aimed at combatingracism, world governing body FIFA said on Tuesday.

In a statement following a meeting of the International Football Association Board (IFAB) in Vancouver,FIFAconfirmed that the rule was one of two law changes that would be introduced at this year's World Cup.

"At the discretion of the competition organiser, any player covering their mouth in a confrontational situation with an opponent may be sanctioned with a red card," FIFA said in a statement.

The new rule follows controversy earlier this year when Benfica winger Gianluca Prestianni was accused of racially abusingReal Madridstar Vinicius Junior during aChampions Leaguegame in February.

Prestianni was accused of calling Vinicius a "monkey" repeatedly while covering his mouth. Prestianni denied racially abusing Vinicius but was later banned for six matches with three of those suspended for "homophobic conduct".

FIFA PresidentGianni Infantinohad voiced support for the law change in an interview with British broadcaster Sky News last month.

"If a player covers his mouth and says something, and this has a racist consequence, then he has to be sent off, obviously," Infantino said.

"There must be a presumption that he has said something he shouldn't have said, otherwise he wouldn't have had to cover his mouth.

"If you do not have something to hide, you don't hide your mouth when you say something. That's it, as simple as that."

In a separate law change announced on Tuesday to be enforced at the World Cup, FIFA said that red cards would also be introduced for players leaving the field of play in protest at a referee's decision.

"At the discretion of the competition organiser, the referee may sanction with a red card any player who leaves the field of play in protest at a referee's decision," FIFA said.

"This new rule will also apply to any team official who incites players to leave the field of play."

FIFA said a team causing a game to be abandoned will forfeit the match.

The move follows the uproar at this year's final of theAfrica Cup of Nations, when Senegal's players, head coach Pape Thiaw and his staff walked off the pitch in Rabat afterMoroccowere awarded a penalty in added time, which forward Brahim Diaz ultimately missed.

Senegal went on to win the final 1-0 in extra time, but were sensationally stripped of the title by the Confederation of African Football (CAF) in a bombshell decision issued last month.

The law changes came as FIFA delegates gathered in Vancouver ahead of Thursday's FIFA Congress, the final gathering offootball's global governing body before the World Cup gets underway inCanada,Mexicoand theUnited Statesin June.
