Why Covering Your Mouth Results in a Red Card at the 2026 World Cup

During the June 20 clash between Paraguay and Turkey, Miguel Almirón made World Cup history by becoming the first player ever to receive a red card for covering his mouth while speaking to an opponent. This new enforcement comes after FIFA introduced a rule before the 2026 tournament aimed at preventing players from hiding their words during heated exchanges.

The Reason Behind the Rule

This change was prompted by an incident earlier in 2026 during a Champions League match between Real Madrid and Atletico Madrid. Atletico's Gianluca Prestianni covered his mouth while talking to Vinicius Jr., sparking accusations of racial abuse. However, because the player's mouth was obscured, there was no way to confirm what was said. The confusion led UEFA to urge FIFA to implement a clear policy to avoid similar controversies.

At an April meeting of the International Football Association Board (IFAB), a new rule was agreed upon: any player caught covering their mouth during a confrontation with an opponent would receive an automatic red card. The rationale is straightforward—covering the mouth makes it impossible to verify statements, which could be offensive or abusive.

FIFA's Explanation

Following a VAR review in the Türkiye vs. Paraguay match, Miguel Almirón was sent off for this exact offense. FIFA emphasized that the rule aims to uphold transparency and fairness on the pitch by eliminating actions that hide communication.

Context from the Champions League Incident

The controversy started in February when Prestianni and Vinicius Jr. clashed during the Champions League. Play was halted for ten minutes after Vinicius claimed Prestianni used racist language. Later, teammate Eduardo Camavinga suggested the comment was homophobic instead. Prestianni denied the accusations, stating Vinicius misunderstood him. Without clear evidence, UEFA suspended Prestianni for several matches but called on FIFA to create a rule that prevents such ambiguity in the future. Fans now refer to this as "The Prestianni Law."

Other Instances of the New Rule Being Applied

Almirón’s sending off marked the first time this rule was enforced at the World Cup, but he wasn’t the only one penalized. On June 30, Colombia’s Piero Hincapie also received a red card late in the game against Mexico for covering his mouth during a verbal exchange. His ejection came during stoppage time of a 2-0 defeat, showing the rule's strict application throughout the tournament.
