In the World Cup, referees have been issuing red cards to players who cover their mouths while confronting opponents. This action is a result of a new rule that was communicated to players before the tournament.

The rule states that players will receive an immediate red card for covering their mouth during verbal confrontations with other players. Officials are enforcing this rule change, as seen in recent incidents.

Further details about this new rule and its enforcement can be found through ValleyCentral sports news.
