2026 World Cup Regulations: 23-26 Players in Final Rosters, Official Approval Starts June

In preparation for the historic 48-team 2026 World Cup, FIFA has detailed the logistical framework for player registration. Participating nations in 2026 will provide internal lists before confirming their final 26-man squads by June 2nd. The 2026 rules permit emergency injury replacements from the preliminary pool up to 24 hours before kick-off. Notably, goalkeeper substitutions for severe health reasons are allowed throughout the 2026 competition. This update solidifies the transition from the traditional 23-player limit to the more flexible 26-player format, ensuring teams are well-equipped for the expanded 2026 schedule across the USA, Canada, and Mexico.
