Mexico and South Africa’s 2026 World Cup opener will be remembered for all the wrong reasons after a chaotic contest produced three red cards, joining an infamous list of the tournament’s most ill-disciplined matches.

Played at the Estadio Azteca, the 2-0 win for Mexico saw South Africa reduced to nine men and a late dismissal for Mexico’s César Montes added further controversy. Referee Wilton Sampaio also issued a series of cautions in a game that quickly spiralled into disciplinary chaos.

The match immediately entered World Cup record discussions as the first-ever opening fixture to feature three sendings-off, but it still fell short of the most card-heavy games in tournament history.

Below is a ranked look at five of the most red-card-filled matches ever played at the World Cup.
