Covering Your Mouth During a Confrontation: a World Cup Trial, Not a Law
Covering your mouth while speaking to an opponent during an on-field confrontation is a direct red card at the 2026 World Cup, regardless of what is actually said. It is a tournament provision being tested there and it is not part of the Laws of the Game: the word “mouth” appears nowhere in the 2026/27 edition. Outside a competition that has adopted it, there is no such offence.
No sanction existed, and none exists in the Laws today. Without being able to prove what was said, referees had no real way to act on suspected verbal abuse hidden this way.
At the 2026 World Cup, covering the mouth while speaking to an opponent during an on-field confrontation is a direct red card, regardless of the content of what was said. The covering itself is the offence. This applies because the tournament adopted it for testing, not because the Laws require it.
What changed
Nothing changed in the Laws. There is no specific sanction in the Laws of the Game for covering your mouth while talking to an opponent, and there was none before: players could exchange words during confrontations without consequence unless the referee could establish what was said, which was usually impossible to prove. What changed is that the 2026 World Cup adopted a provision, for testing, making the covering itself the offence, which sidesteps the need to lip-read or translate disputed remarks in real time.
Why it matters
The provision was introduced after a Champions League incident in which a player was accused of making discriminatory remarks toward an opponent while hiding his mouth with his shirt, an incident the referee could not act on because the remark itself couldn't be verified. By punishing the concealment rather than the speech, officials no longer need to determine what was said, only whether a player deliberately covered their mouth while addressing an opponent during a confrontation. At the 2026 World Cup, Paraguay's Miguel Almiron became the first player sent off under it, in a Group D match against Türkiye, for covering his mouth while exchanging words with Mert Müldür. Paraguay coach Gustavo Alfaro accepted the decision but argued a yellow card would have been proportionate, reflecting some unease in the game about how strictly it is applied. Whether it ever becomes a Law is a separate question, and it is not one yet.
Scenarios
Player covers mouth during a heated exchange
Two players exchange words after a foul. One of them covers his mouth with his hand while speaking to the other, who appeals to the referee.
Player wipes mouth or face without addressing an opponent
A player wipes sweat from his face or mouth during play, with no confrontation or exchange of words with an opponent happening at that moment.
