The 2026 FIFA World Cup arrives not just with a bigger stage of 48 teams, three host nations, 104 matches, but a plethora of rule changes as well. The International Football Association Board (IFAB), football’s apex law-making authority, has pushed through a sweeping number of reforms that will reshape how the upcoming FIFA World Cup set to be played across the United States, Canada, and Mexico from Thursday (Jun 11). These rules empower referees with enough say to send a player back if they cover the mouth on pitch among others. Seven changes, in particular, will define exactly what kind of football the world sees in 2026.
Expanded VAR decisions
VAR has become and integral part of the game and the FIFA World Cup 2026 will see expanded usage of the technology for the following instances:
- Attacking fouls that happen before play
- Incorrectly awarded corner kick without delaying start
- Wrongly issued red card stemming from second yellow card
- Wrong player handed yellow card
Red cards for covering mouths
Referees are allowed to issue red card to players who cover their mouth during the confrontation. The friendly chatter is allowed though. The rule came into force in the aftermath of Champions League drama where Benfica player Gianluca Prestianni racially abused Real Madrid's Vini Jr. with a covered mouth.
