FIFA Introduces New Offside Technology Ahead of 2026 World Cup

FIFA has officially confirmed the introduction of a new semi-automated offside technology for the 2026 FIFA World Cup, a move aimed at reducing delays, unnecessary play, and injury risks caused by late offside decisions.

Under the new system, assistant referees will receive an automatic alert whenever a player is detected to be more than 10 centimetres offside. The alert will allow officials to raise their flags earlier rather than waiting for an attacking move to be completed before making a decision.

The change is expected to address one of the most common frustrations in modern football, where assistant referees are instructed to delay offside calls during promising attacks to allow VAR to review the incident if necessary.

By identifying clear offside situations earlier, FIFA hopes to reduce situations where players continue sprinting, tackling, or competing for the ball despite an obvious offside infringement, thereby lowering the risk of avoidable injuries.

Despite the introduction of the technology, human officials will continue to have the final say on every decision. Assistant referees and VAR officials will be able to disregard an alert if they believe there is an issue with the situation or the technology’s assessment.

FIFA has also clarified that the system is not designed to rule on marginal offside situations or subjective decisions. Close offside calls, as well as incidents involving interpretations such as whether an attacking player interfered with an opponent or gained an advantage from their position, will still require human judgment.

The new technology forms part of FIFA’s continued efforts to improve officiating accuracy and efficiency ahead of the 2026 World Cup, which will be hosted across the United States, Canada, and Mexico.
