Earlier this month, Vitor Belfort submitted to a blood and urine test requested by the Nevada Athletic Commission.
According to a report by ESPN, Belfort passed both tests free of any banned substances or extra testosterone. He is scheduled to face Chris Weidman for the UFC middleweight title on February 1 at UFC 184.
As part of his requirements by the NAC, Belfort is subject to random testing leading up to the fight. However, the bout will now take place in Los Angeles and be overseen by the California Athletic Commission.
Bob Bennett, executive director with the NAC, stated that Belfort tested negative for all banned substances and his blood serum testosterone levels were within normal range.
