The World Cup clash between the USA and Australia turned into a true battle of nerves, forcing head referee Felix Zwayer to take strict measures. The German official issued a total of seven cards during the match in Seattle, officially making him the referee with the most official warnings in a single game since the start of the current World Cup. However, the match will also be remembered for an incredibly bizarre moment in added time. The immense pressure took its toll, and Zwayer himself suffered a severe cramp, collapsing on the pitch. Players had to administer first aid and stretch his leg so he could even finish the game.
Before this electrifying encounter, the title for the "roughest match" of the 2026 tournament was held by the Mexico vs. South Africa game, which ended 2-0. In that match, however, the progression was different – referee Wilton Sampaio showed a total of six cards, but they were evenly distributed: three yellow and three direct red cards, which left a significant mark on the game. Zwayer and the players from the USA and Australia, however, quickly surpassed this metric in terms of the total number of official warnings.
As tense as these matches may seem, they are far from the absolute records in World Cup history. The most yellow cards in a single match – an astonishing 18 – were shown during the legendary and extremely heated clash between the Netherlands and Argentina at the 2022 World Cup in Qatar. However, if we talk about the total number of cards and chaos on the field, the undisputed leader remains the so-called "Battle of Nuremberg" from 2006. In that legendary Round of 16 match between Portugal and the Netherlands, Russian referee Valentin Ivanov issued a record 16 yellow and 4 red cards, making it the most undisciplined match in football history.
