FIFA began an assessment of video assistant referee changes after flawed VAR rulings tarnished the competition, with Switzerland’s mistaken red card for a player. That error involving a challenge, where VAR confused the offender’s identity, sparked strong criticism from pundits. UEFA also said it would exclude VAR for calls on simulation at the World Cup, due to confusion under the updated system’s rules. The mistakes in key matches have prompted FIFA and IFAB to reassess VAR protocols to prevent similar problems in upcoming games.
