Key Takeaways:
- FIFA will introduce advanced semi-automated offside technology at the 2026 World Cup, enhancing accuracy and reducing delays
- AI-driven 3D avatars will digitally scan all 1,248 players across 48 teams for clearer offside decisions
- New tech will provide 3D ball position animations and real-time line-of-sight feeds following recent controversial incidents
Innovative Offside Technology Set for World Stage
FIFA is set to revolutionise offside decision-making at the 2026 World Cup by integrating advanced semi-automated offside technology designed for faster, more accurate judgments. This system builds upon those previously trialled at the Club World Cup and Intercontinental Cup, but significantly increases sensitivity: a real-time audio alert will notify assistant referees when a player is detected to be more than 10 centimetres offside – an improvement over the former threshold of 50 centimetres.
This advancement aims to let assistant referees raise the flag without the need to delay until the conclusion of a phase of play. Nevertheless, the official will retain full authority to determine when play is stopped, with FIFA confirming that numerous failsafe measures are in place to mitigate technical malfunctions. If the assistant suspects a system issue, they may keep the flag down as a precaution.

Despite its benefits, the technology does have limitations: it cannot always resolve extremely tight offside calls, particularly in crowded penalty areas or when players are grounded. Its application is restricted to clear positional offences and will not extend to subjective decisions requiring interpretation, such as assessing whether a player without the ball has interfered with an opponent.
FIFA’s ambition is to address common frustrations among fans and players, while also reducing unnecessary play that can result in injuries. The case of Nottingham Forest forward Taiwo Awoniyi, who was placed in an induced coma in May 2025 following a collision with a post when an offside flag was delayed, has underscored the potential safety benefits of the new approach.
Player Scanning and AI Avatars for Precision Calls
For the first time, FIFA will employ sophisticated, AI-driven 3D avatars to improve the precision of offside determinations. Each of the 1,248 players spanning the 26-man squads from all 48 participating teams will undergo a rapid scanning process, taking approximately one second during their pre-tournament photo session.
These highly detailed scans will allow for the creation of lifelike digital avatars and produce clearer, enhanced animations for each offside call at the tournament.
| New Technologies at 2026 World Cup | Key Features |
|---|---|
| Semi-Automated Offside | Audio alert for >10cm offside, rapid flag raising |
| AI 3D Avatars | All 1,248 players scanned for accurate digital modelling |
| 3D Ball Position Animation | Tracks ball to determine if it has gone out of play |
| Line-of-Sight Feeds | Provides VAR and TV with goalkeeper perspectives |
Ball Tracking and Enhanced VAR Tools
In response to recent disputes FIFA has greenlit technology capable of conclusively showing if the ball crossed the touchline before a goal. This includes 3D animations similar to those already used in goal-line technology, precisely illustrating the ball’s location relative to the line.
A sensor embedded in the match ball will also identify the player who last touched the ball, empowering VAR to verify correct corner calls and other critical decisions within their extended role.
Additionally, FIFA’s ‘Real-time 3D Recreation’ innovation has been expanded to enable more accurate line-of-sight judgments for offside rulings. Two virtual feeds will simultaneously replicate the perspective of each goalkeeper, accessible both to VAR officials and television audiences. This development is aimed at clarifying whether a goalkeeper’s view has been obstructed during marginal offside incidents, which proved contentious in multiple matches during the current season.
