FIFA is set to introduce advanced semi-automated offside for video assistant referees (VAR) at the 2026 World Cup.
This will enable officials make decisions faster and mean an assistant can raise the flag rather than wait for a move to play out.
A real-time audio alert will be sent to the assistant if a player is more than 10cm offside.
Previous versions of the technology tested at the Club World Cup and the Intercontinental Cup only notified the officials if a player was greater than 50cm offside.
The official will remain in charge of when to raise the flag and stop play. They may keep the flag down if they suspect there has been a malfunction, but Fifa says a series of failsafe measures are in the technology to prevent errors happening.
The technology will still be unable to pick out the closest offsides, while there are limitations if players are on the ground or if there are several too close together.
It can only be used for positional offside and not for subjective calls, those which require interpretation around whether a player has interfered with an opponent without touching the ball.
FIFA hopes it will remove some of the frustration felt by supporters and players, and reduce the chance of injury due to needless passages of play when an offside flag is going to be raised.
