A Brazilian U20 soccer match between Mamore and Uberlandia made headlines for an unprecedented display of on-field aggression, culminating in a record-setting 51 red cards. The incident shattered the previous Guinness World Record of 36 red cards, which was set in Argentina's fifth division in 2011.

The chaos erupted after Mamore scored their third goal, with a player making provocative gestures and uttering expletives towards the opposing team's bench, according to the referee's match report.

What followed was an all-out brawl that involved players and staff from both teams. Referees struggled to regain control, issuing red cards indiscriminately. Of the 51 total red cards, 48 were a direct result of the brawl. One player had already been sent off for a second yellow card earlier in the match, and two more received red cards afterward for threatening an official and striking an opponent, respectively.

Despite the mass ejections, the match reportedly continued. The incident has drawn widespread attention, casting a shadow over the sport but also generating significant discussion.
