What is VAR, the technology being used for 1st time in WC?
Video assistant referee (VAR) technology, which is being used in a FIFA World Cup for the first time, aids on-field referees using replays. The VAR team, which has access to over 30 camera angles, supports referees from a centralised video operation room. The technology can only be used for decisions relating to goals, penalties, red cards and mistaken identity cases.
