Argentinian referee Yael Falcón Pérez oversaw his first match as a FIFA official during the Sweden versus Tunisia game at the 2026 World Cup qualifying event in Monterrey. The match was largely without incident, with Falcón Pérez maintaining firm control throughout. The only significant moment came in the 4-1 victory for Sweden, when a goal initially flagged for offside by assistant referee Facundo Rodríguez was overturned following a review by the Video Assistant Referee (VAR).
