Overview

• The Football Video Support system grants each team two challenges per match, with an extra in extra time, limited to goals, penalties, direct red cards and mistaken identity, and only successful challenges are retained.
• In the Korea–Ukraine opener, South Korea’s penalty appeal was rejected after review, then a Ukrainian request saw a South Korea goal overturned for offside by referee Keylor Herrera.
• Argentina coach Diego Placente lost both early challenges against Cuba as referee Muhammad Nazmi bin Nasaruddin upheld a direct red to Santiago Fernández and later declined a penalty.
• Coaches initiate reviews by showing a physical card to the fourth official, prompting the referee to check a pitchside monitor without a remote VAR crew.
• FIFA and refereeing officials, including Pierluigi Collina, frame the trial as a simpler, cheaper option to traditional VAR and are collecting usage data and reactions throughout the event.
