A first happened in the Round of 16 match between the Portland Timbers and FC Cincinnati.
For the first time fans were given the opportunity to listen to the conversation between a referee and a Video Assistant Referee during a live match.
It happened in the 62nd minute after Mathieu Deplagne scored a goal to give FC Cincy a 1-0 lead. But on replay, it was clear that Deplagne was offside and VAR Rosendo Mendoza buzzed down to referee Armando Villarreal. You can hear their conversation and their final decision below.
