Video Assistant Referee (VAR)
An off-field official in football who reviews video replays to help the on-field referee correct clear and obvious errors in key match situations.
VAR stands for Video Assistant Referee.
Definition
The video assistant referee (VAR) is an official, supported by assistants and replay operators, who watches match footage from a video operation room and communicates with the on-field referee. VAR is designed to intervene only for clear and obvious errors, or serious missed incidents, in four categories: goals and the build-up to them, penalty decisions, direct red-card incidents, and cases of mistaken identity.
When a possible error is flagged, the referee may accept the VAR's advice or view the footage personally at a pitchside monitor before making the final decision, which remains the referee's own. The system aims to reduce match-changing mistakes without stopping play for marginal judgement calls. VAR is specific to football; other sports use their own review technologies, such as cricket's Decision Review System or tennis electronic line-calling.
