The 2026 World Cup, already set to revolutionize the tournament with an expansion to 48 teams, is introducing significant changes to player discipline on the field. FIFA has announced two new red card rules following a series of recent incidents that raised concerns about player behavior. With the tournament being hosted across the United States, Canada, and Mexico, it is already a major departure from past World Cups, and these new rules add another layer of complexity.
Mouth-Covering Confrontations to Be Punishable by Red Card
One of the central changes allows referees to send off players who cover their mouths while confronting an opponent. This gesture has become increasingly common in modern football and has drawn scrutiny in the context of abuse allegations. The push for this rule gained momentum after an incident involving Vinícius Júnior of Real Madrid and Gianluca Prestianni of Benfica during a Champions League knockout playoff match in February 2026. During that game, Vinícius accused Prestianni of racially abusing him, with the Benfica player seen speaking while covering his mouth with his shirt. Vinícius immediately alerted referee François Letexier, and the match was halted for 10 minutes under UEFA protocols. Prestianni denied the allegation and later stated that he had used an anti-gay slur in Spanish rather than a racist term. UEFA confirmed that both forms of discriminatory language fall under the same disciplinary framework and subsequently issued Prestianni a six-match ban for discriminatory conduct, with three matches suspended for two years and one already served provisionally. The sanction remains subject to appeal.
Following that incident, FIFA formally proposed tightening sanctions, and the matter was taken to the International Football Association Board (IFAB), which determines the Laws of the Game. At a meeting in Vancouver, British Columbia, IFAB approved the change by unanimous agreement, introducing a provision that allows competition organizers to impose red cards in such situations. An IFAB statement said: "At the discretion of the competition organizer, any player covering their mouth in a confrontational situation with an opponent may be sanctioned with a red card." FIFA President Gianni Infantino had earlier indicated his support for the measure, telling Sky News after IFAB's February meeting in Wales that he believed players should be dismissed if they confront opponents while covering their mouths.
Walking Off in Protest Will Now Trigger Instant Dismissal
The second major change addresses situations where players leave the pitch in protest at refereeing decisions. FIFA is moving to impose immediate red cards for such actions during the World Cup. The rule will also extend to officials who encourage or incite players to leave the field, broadening the scope beyond individual misconduct to include collective behavior. Under the updated approach, any team responsible for causing a match to be abandoned would, in principle, forfeit the game, reinforcing the consequences of such actions within the tournament structure. This decision is directly linked to events at the 2025 Africa Cup of Nations final, played on January 18, 2026, involving the Senegal national football team and the Morocco national football team. During that match, Morocco was awarded a penalty deep into stoppage time following a foul on Achraf Hakimi, prompting Senegal players to walk off the pitch in protest. The interruption lasted approximately 17 minutes before the players returned. Although Brahim Díaz missed the penalty, the game continued into extra time, where Pape Gueye scored to give Senegal a 1-0 win on the field. However, the Confederation of African Football (CAF) later ruled that Senegal's walk-off constituted a breach of competition regulations, overturning the result and awarding Morocco a 3-0 technical victory. Senegal has since challenged that decision at the Court of Arbitration for Sport, with the case still ongoing.
Limited Application for Now, Wider Adoption Requires IFAB Approval
Although both rule changes will be enforced at the 2026 World Cup, they are not yet permanent additions to the global Laws of the Game. For either measure to be adopted universally across domestic leagues and international competitions, they would need to be formally integrated into IFAB's rulebook beyond the current tournament-specific application. FIFA has indicated that these measures are being introduced in response to recent incidents and evolving concerns around player behavior, with the World Cup serving as a controlled environment to implement and assess their impact.
Tournament Context: Expansion and Hosting Structure
The disciplinary changes come as part of a bigger shift for the 2026 World Cup, which will expand to 48 teams and introduce a new group-stage format before heading into a 32-team knockout round. The United States will host 78 of the 104 matches, including all fixtures from the quarter-finals onward, while Canada and Mexico will each stage 13 matches. Alongside this, FIFA will introduce two yellow card reset points to reflect the longer format, with bookings wiped after the group stage and again after the quarter-finals, ensuring players are less likely to miss decisive matches due to accumulated cautions earlier in the tournament. With multiple layers of change already built into the competition, the introduction of stricter red card rules reflects an effort to shape behavior on the pitch in line with those wider adjustments.
