Football is about to change in ways most fans have not yet registered. With the 2026 World Cup kicking off in Mexico on June 11, the International Football Association Board has confirmed a set of rule changes that will reshape the game in both large and small ways. Some fix long-standing problems. Others will generate controversy from the first whistle. Here is what every fan needs to know before the tournament starts.
VAR Gets New Powers - Including for Corners
The biggest shift is an expansion of what VAR can review. For the first time, the technology can intervene when corner kicks have been incorrectly awarded. This means a goal that began with a wrongly-given corner can be disallowed after review. VAR will also step in when a red card results from mistaken identity, and when a foul is committed before play restarts from a set piece. These are genuine loopholes that have affected major matches for years.
There is also a new red card offence for any player who covers their mouth with a hand, arm or shirt during a confrontation - a move designed to prevent undetectable communication. Players who walk off the pitch in protest of a refereeing decision will also be sent off, and teams that cause a match to be abandoned will automatically forfeit the result.
Substitutions and Time-Wasting
Outgoing players have 10 seconds to leave the pitch from the moment the substitution board is raised. They must exit at the nearest boundary line. This directly targets the theatrical slow-walk that has become standard in big matches. For throw-ins and goal kicks, referees will begin a five-second visual countdown. Fail to take the restart in time and possession transfers to the opposition.
Mandatory Hydration Breaks
Every World Cup match will include a mandatory three-minute hydration break in each half, at a time of the referee's choosing. Given the summer heat at venues across the United States and Mexico, FIFA sees this as a health measure. It is unusual for football but not unprecedented in other sports. Whether it disrupts momentum in tight games will be one of the tournament's talking points.
Rules context: All changes confirmed by IFAB and approved by FIFA for implementation from World Cup 2026 onwards. Domestic leagues globally will adopt the new rules from the 2026-27 season. Tournament begins June 11, 2026 at Estadio Azteca, Mexico City.
