The 2026 World Cup is set to debut with a newly expanded format and venues spanning across Mexico, the United States, and Canada. Along with these changes, a set of new football rules has been approved by the International Football Association Board (IFAB) during its annual assembly held in Cardiff. These rules are designed to accelerate the pace of the game, curb tactical delays, and broaden the scope of video assistant referee (VAR) interventions, taking effect from June 1, just in time for the World Cup.

The modifications notably impact four areas: referee reviews, injury management, substitutions, and game restarts. One of the significant changes allows the VAR to intervene in two additional scenarios during the World Cup. This includes reviewing situations involving second yellow cards leading to ejections when deemed 'clearly incorrect' and corner kicks awarded incorrectly, provided that the review happens immediately and does not delay the game. These updates reflect a wider initiative to enhance the overall quality and fairness of football matches.

Furthermore, the expansion of VAR's purview signifies a proactive approach to tackling errors that can affect match outcomes. By introducing these new rules, FIFA aims to create a more fluid and dynamically engaging tournament experience for players and fans alike, potentially transforming the way the game is played and officiated on the global stage.
