Format changes and new regulations for the 2026 FIFA World Cup

The 2026 FIFA World Cup will introduce significant changes, featuring an expanded format with 48 teams divided into 12 groups. The tournament duration is extended to 39 days, with the total number of matches rising to 104, including a new qualification process for the eight best third-placed teams. New rules include a 10-second limit for player substitutions, with a one-minute penalty for delays, and a 5-second timer for throw-ins and goal kicks to prevent time-wasting. Players receiving on-field medical treatment must leave the pitch and wait one minute before returning. Furthermore, only team captains are permitted to approach referees, with others facing potential yellow cards for surrounding them. Finally, the role of VAR is expanded to penalize "screening" or blocking tactics during set pieces, which may result in disallowed goals.
