The Video Assistant Referee (VAR) system will be used in the FA Cup for the first time in Monday night's third-round tie between Brighton and Crystal Palace. Here is how it will work.
WHAT INCIDENTS CAN THE VAR REVIEW?
Only goals, straight red cards, penalties and mistaken identity will be reviewed by the VAR, who will watch the game from Stockley Park studios in Middlesex along with their assistant (AVAR) using a direct feed from all the TV cameras.
They can also assist in judging encroachment when a penalty is taken — if the player encroaching directly influences the outcome.
