The FIFA World Cup 2026 is set to be the biggest tournament in football history, featuring 48 teams and more than 100 matches across the United States, Canada, and Mexico. However, it is not only the format that will be different. Fans will also witness several major law changes designed to improve fairness, speed up matches, and reduce controversial incidents.
Football lawmakers at IFAB (International Football Association Board) have approved a number of new regulations that will make their debut during the World Cup. From expanded Video Assistant Referee (VAR) powers to stricter measures against timewasting, these changes could have a significant impact on how matches are played and officiated.
For Cambodian football fans preparing to watch World Cup 2026, here is a complete breakdown of the most important new rules.
Expanded VAR Powers Take Center Stage
One of the biggest talking points is the expanded role of VAR.
Since its introduction at the 2018 World Cup, VAR has become one of football’s most debated technologies. FIFA believes it is now time to broaden its responsibilities in order to eliminate more obvious mistakes.
VAR Can Review Incorrect Corner Decisions
Previously, VAR could not intervene if a referee mistakenly awarded a corner kick.
Under the new rules, VAR can now step in when an incorrect corner decision is made, provided the correction can happen quickly without causing unnecessary delays. This change aims to prevent goals resulting from wrongly awarded corners.
Second Yellow Cards Can Be Reviewed
Another significant adjustment allows VAR to review incidents involving second yellow cards.
Before 2026, VAR could only intervene for direct red cards. Now, officials can examine situations where a player may have been incorrectly shown a second yellow card that results in a dismissal. However, VAR cannot recommend a second yellow card if one was not originally given by the referee.
Set-Piece Incidents Receive Greater Scrutiny
VAR will also monitor fouls committed before corners and free-kicks are taken.
This adjustment specifically targets pushing, grappling, and shirt-pulling inside the penalty area before the ball enters play. Referees may now review incidents that previously went unnoticed.
FIFA Declares War on Timewasting
One of the most common complaints from football fans is excessive timewasting.
World Cup 2026 introduces several measures designed to keep the game moving and reduce unnecessary delays.
Five-Second Countdown for Restarts
Referees will now use visible countdowns for throw-ins and goal-kicks.
If a team fails to restart play within five seconds:
- Throw-ins may be awarded to the opposition.
- Delayed goal-kicks could result in a corner kick being awarded to the opposing team.
The objective is to increase the tempo of matches and discourage teams from wasting valuable minutes.
Tactical Goalkeeper Timeouts Are Targeted
In recent years, some teams have used goalkeeper injuries as an opportunity for unofficial coaching breaks.
FIFA officials have made it clear they want to prevent this tactic. During treatment for goalkeepers, outfield players will no longer be allowed to gather around their coaches for tactical discussions.
New Substitution Rules
Substitutions are also receiving stricter regulations.
Players Must Leave Quickly
Once the substitution board is displayed, the departing player has only 10 seconds to leave the field.
The player must exit using the nearest boundary line rather than walking slowly across the entire pitch. If they fail to comply, the incoming substitute may be forced to wait until the next stoppage after one minute has elapsed.
This change directly targets players who deliberately waste time when protecting a lead late in matches.
New Medical Treatment Rules
Another major adjustment concerns injured players.
When medical staff enter the field to treat an outfield player, that player must remain off the pitch for at least one minute after play restarts. Exceptions apply for serious injuries, head injuries, goalkeeper incidents, and penalty situations.
The goal is to discourage players from exaggerating injuries simply to slow the game down.
Hydration Breaks Added for Player Safety
World Cup 2026 is expected to feature high temperatures across several host cities.
To protect players, FIFA has introduced mandatory hydration breaks during each half. These three-minute pauses will allow players to cool down and reduce health risks associated with extreme weather conditions.
Why These Changes Matter
The overall objective behind the new laws is simple: improve the quality of football while increasing fairness and entertainment.
FIFA and IFAB believe expanded VAR reviews will reduce major refereeing errors, while stricter timewasting rules will keep matches flowing at a faster pace. For supporters, this should lead to more active playing time and fewer frustrating delays.
As the world prepares for the largest World Cup ever staged, these law changes could become one of the defining stories of the tournament.
For Cambodian football fans, understanding these new rules will make watching World Cup 2026 even more exciting, as players, coaches, and referees adapt to a new era of football.
