A new rule is being enforced at the World Cup, resulting in immediate red cards for players who cover their mouths when verbally confronting opponents. This rule change was communicated to players before the tournament began.

Officials are actively enforcing this new rule, and it has already led to incidents during the games. One such incident occurred on Tuesday night, involving an Ecuador defender.

Further details about this rule and its enforcement can be found through local news sources, such as KPRC 2 and Click2Houston, which provide updates on the World Cup and its developments.
