FIFA has changed the red card rules in the World Cup for 2026, adding two new send-off triggers for players who cover their mouths in a confrontation or deliberately walk off in protest. The tournament is moving from 32 teams to 48 teams, and that adds more matches where discipline can swing a roster.
Gianluca Prestianni and Vinicius Junior
The mouth-covering rule follows a February Champions League match involving Gianluca Prestianni and Vinicius Junior, when the Benfica player covered his mouth with his jersey while directing abuse at the Real Madrid star. Under the new World Cup rule, a referee can now show a red card for that conduct outright.
FIFA also added a walkoff rule after a January Africa Cup of Nations final in which Senegal’s players left the field for nearly 15 minutes to protest a penalty call. That same rule now reaches coaches or team officials who encourage players to walk off, turning a protest tactic into send-off territory at the 2026 World Cup.
FIFA Yellow Card Reset
The discipline structure is also different from the last 32-team format. Yellow cards reset twice at the 2026 World Cup instead of once, so any player carrying one out of the group stage starts the knockout round fresh, and the same reset happens after the quarterfinals.
That does not wipe out every suspension risk. A player can still be sent off immediately for collecting two yellow cards in the same game, and a red card still brings a one-game suspension at minimum.
FIFA’s disciplinary committee can go further if an offense is serious enough, adding more games to the suspension or issuing a fine. The list of straight-red offenses also still covers dangerous fouls, violent conduct, spitting, biting, offensive language and denying a clear goal-scoring opportunity.
World Cup Discipline Risk
The practical effect is simple: players, coaches and team officials have fewer places to hide a protest and fewer gray areas around confrontation. At the same time, the twice-reset yellow-card system gives teams a clean slate twice, but not before a player can be suspended for two yellow cards in one match.
For teams heading into the 2026 World Cup, the next step is discipline management, not guesswork. A mouth covered in a confrontation or a deliberate walkoff can now end with a red card as fast as a dangerous tackle, and that changes how quickly a dispute can turn into a suspension.
