James Krause betting controversy
Just before the event took place, the UFC was informed by sources that suspicious betting patterns had been observed for the fight between Darrick Minner and Shayilan Nuerdanbieke. Hours before the fight, Nuerdanbieke's odds to win moved significantly in his favor, thus causing the Nevada State Athletic Commission to open an investigation.[19] Suspicion arose when Minner, coached by UFC veteran James Krause, threw a kick and showed signs of injury to his leg, kicking with that same leg once more before being finished by technical knockout seconds later. This caused many to speculate that Minner knowingly fought with an injury and purposely lost the fight, and that Krause, who had been very open about betting on fights, placed a bet on Nuerdanbieke. On November 18, the Nevada State Athletic Commission informed the UFC and Krause that Krause’s license was suspended and would remain so during the course of the investigation. The UFC also announced that any fighter who chose to continue to be coached by Krause or who continued to train in his gym would be banned from participating in future UFC events until the investigation concludes.[20]
