All drug tests conducted at UFC Fight Night “Bigfoot vs. Mir” came back negative, according to a statement released Thursday by the Brazilian MMA Athletic Commission (CABMMA).
All 24 fighters who competed on the card were tested for performance for enhancing drugs and drugs of abuse in a World Anti-Doping Agency-accredited lab, according to the statement. In addition, six fighters were randomly selected and tested for erythropoietin (EPO). All four tests returned negative, but the athletes tested were not identified.
The event took place Feb. 22 at Gigantinho Gymnasium in Porto Alegre, Brazil, and was headlined by a heavyweight showdown pitting Frank Mir against Antonio Silva. Mir finished “Bigfoot” with a flurry of elbows, forcing the hand of referee Mario Yamasaki 1:40 into the first round.
The event also saw Michael Johnson prevail in his return to the Octagon, as “The Menace” outworked Edson Barboza in the evening’s co-main event. Additionally, Sam Alvey emerged victorious on the main card, scoring a knockout of Cezar Ferreira.
The Las Vegas-based organization will return to Brazil on March 21, when UFC Fight Night “Maia vs. LaFlare” goes down in Rio de Janeiro.
