IFAB has rewritten chunks of the rulebook for the 2026 World Cup — and the changes are more sweeping than anything we've seen at a tournament in years. Time-wasting, dark arts at set-pieces, protest walk-offs: it's all being addressed. Some of it is overdue. Some of it will cause chaos in the first week.
Here's what's changing and why it matters.
Cracking down on set-pieces and time-wasting
The biggest tactical shift concerns corners. Previously, VAR could only flag a foul once the ball was in play — meaning any shoving, shirt-pulling, or obstruction in the box before delivery was effectively unpunishable unless it spilled over into open play. That loophole is closed. VAR can now intervene for fouls committed before a corner is even taken, with the set-piece potentially retaken and disciplinary action on the table.
Given how dominant set-piece coaching has become — and how much of it relies on masking illegal movement — this single change could alter the way teams set up their routines entirely. Corners suddenly got riskier to cheat at.
The time-wasting crackdown goes further. Substitutions will now operate under a 10-second countdown for the departing player to exit via the nearest perimeter. Fail to comply, and the incoming player waits until the next stoppage at least a minute later — leaving their team short. This was tested in MLS and has already produced results: in a Japan vs Iceland friendly, Kristian Hlynsson dawdled off the pitch and Iceland played a man down for 60 seconds. Japan scored the only goal. That's a persuasive pilot study.
Throw-ins and goal kicks get similar treatment. Five seconds to take a throw or restart from a goal kick — referees will signal the countdown openly so no one can feign ignorance. Slow goalkeeper? Opposition gets a corner. That's a significant deterrent.
Players receiving treatment on the pitch will also be required to stay off the field for at least one minute after play resumes. Goalkeepers, head injuries, and players about to take a penalty are exempt.
Red cards, VAR tweaks, and the mouth-covering rule
VAR's role in yellow cards remains limited — but it's expanding slightly. The video official can now intervene in cases of mistaken identity for a second yellow, or when a "clear and obvious error" has been made. It cannot step in when a second yellow should have been shown but wasn't. That's a narrow window, but it could save a player from an unjust sending-off at a crucial moment.
Two new red card offences are harder to argue with. Any player who covers their mouth during a confrontational situation — the tactic used to hide potential abuse from lip-readers and cameras — is off. This rule was directly prompted by the Prestianni-Vinicius Jr incident in the Champions League, where Vini alleged racial abuse that couldn't be verified precisely because Prestianni had obscured his words. Prestianni was later found to have used homophobic language. The rule exists now because of that case.
Players or teams walking off the pitch in protest against a referee decision also face instant red cards — and teams that leave the field and delay the match will forfeit it. The 2025 Africa Cup of Nations final, where Senegal spent 25 minutes in the dressing room following a controversial penalty call, was the obvious catalyst. They won the match in extra time but had their title stripped. At the World Cup, the consequences would be even more immediate.
What this means in practice
Several of these changes address things that have quietly corroded the watchability of top-level football. The goalkeeper tactical-timeout issue — players congregating at the bench while a keeper lies "injured" — is being discouraged, though IFAB admitted it couldn't agree on specific sanctions. Referees will be encouraged to prevent players from leaving the field. Whether that holds under pressure in a World Cup knockout game is a different question.
Taken together, the changes push in one direction: less dead time, less gamesmanship, more actual football. That should, in theory, compress live betting windows and shift match flow toward teams built on pressing and transitions rather than those who've perfected the art of slowing the game down.
The rules are on paper. Enforcement is what will actually define the 2026 tournament. Pierluigi Collina and FIFA's officiating team are betting heavily on referees holding the line — especially in the group stage, when the pressure to let things slide is at its highest. We'll find out fast whether that confidence is warranted.
