FIFA is introducing a quicker offside system for the 2026 World Cup, but it is not removing the assistant referee's role entirely.
Delayed flags have become one of the biggest frustrations in the modern game. Fans understand why assistants wait, but extended passages of play after an obvious offside can still feel needless.
The new technology aims to cut that delay while keeping assistants in charge of the final decision on the pitch.

According to a BBC Sport report , the new semi-automated offside system will be a significant upgrade for assistant referees.
"FIFA will introduce advanced semi-automated offside for video assistant referees (VAR) which should make decisions faster and mean an assistant can raise the flag rather than wait for a move to play out," BBC Sport reported.
They added, "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."
That is the key change. Instead of waiting through a full attack, assistants can get a quicker signal and make the call sooner.
The reduced 10cm threshold also makes the system more sensitive than earlier versions, which should lead to fewer long passages of play after clear offsides.
Importantly, the system will not remove the assistant's authority. They will still decide when to raise the flag and can ignore alerts if they suspect a technical issue.
"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 fail-safe measures are in the technology to prevent errors happening," it continued.
"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," the report concluded.
The system is there to support, not replace, judgment, especially in situations involving interference or crowded penalty areas.
FIFA is also using AI-generated 3D player avatars to make offside decisions clearer for TV viewers. Each player will be scanned before the tournament, so graphics can be more accurate during broadcasts.
The aim is straightforward: faster flags when it is clear, clearer explanations when VAR is needed, and fewer stoppages that everyone knows are coming.
