At the prestigious Pan American Jiu-Jitsu Championship, a competitor was disqualified during the finals for violating what has become known as the “Bill Cooper rule” – a regulation requiring proper boxers beneath the gi.
The incident occurred just moments into what promised to be an exciting final match. As the referee called “Trabalho!” (“Work!”) to encourage action, he noticed something amiss through the side slits of one competitor’s gi pants – he was either not wearing underwear or was wearing inappropriate attire, both violations of tournament rules.
The disqualification immediately sparked discussion among spectators and competitors alike, with many recalling the infamous Bill Cooper incident that inspired the rule. Years ago, Cooper – a highly respected competitor – faced a similar fate in the finals against Otavio Souza when officials discovered he wasn’t wearing underwear.
According to Cooper, his boxers had become soaked with sweat during earlier matches, prompting him to remove them before the final. What seemed like a practical decision at the time led to his unexpected disqualification when the referee noticed skin visible through the side openings of his gi pants – the same method of detection used in this recent incident.
“The side slits on gi pants can act as a window to what underwear you’re wearing – or not wearing in these cases,” explained a tournament official. “It’s a rule that many competitors might not think about, but it’s strictly enforced to maintain decorum during competitions.”
The rule exists primarily for practical reasons. With competitors frequently grabbing pants for grips and the possibility of drawstrings coming undone during intense matches, proper underwear helps prevent unwanted exposure on the competition floor.
While some spectators expressed disappointment at not seeing the match play out based on technical merit, others acknowledged that rules – even the less obvious ones – must be followed, especially at major championships.
For competitors, this serves as an important reminder to familiarize themselves with all tournament regulations, even those that might seem minor. As one coach remarked, “Championships can be won or lost by the smallest details – sometimes even before the first technique is attempted.”
The Pan American Championship continues to be one of the sport’s most prestigious tournaments, known for its high level of competition and strict adherence to rules and traditions within Brazilian Jiu-Jitsu.
