What is the primary responsibility of the video assistant referee during a match?

The primary responsibility of the video assistant referee (VAR) during a match is to provide support to the main referee in specific situations where a review may be warranted. This role includes assisting with decisions related to goals, penalty calls, direct red cards, or mistaken identity in player sanctions. The VAR reviews relevant video footage with the objective of ensuring that the on-field referee has the most accurate information available to make informed decisions, thereby enhancing the overall fairness and integrity of the match.

This support doesn't involve making all final decisions independently; rather, it is collaborative, allowing the main referee to maintain authority while having access to additional resources. This role is critical in maintaining the flow of the game while ensuring significant game-changing decisions can be reviewed accurately and fairly.
