UFC 134 drug test results are in from UFC Vice President of Regulatory Affairs Marc Ratner (via MMAWeekly.com), who yesterday confirmed that six fighters tested for illegal/banned substances after competing at UFC 134: "Silva vs. Okami" on Aug. 27 have all passed with flying colors.
Because the UFC isn't beholden to an athletic commission in Brazil, they took matters into their own hands.
Main event participants Anderson Silva and Yushin Okami, as well as four other fighters competing on the card, were all screened for performance enhancers such as steroids and drugs of abuse like cocaine and marijuana, among others.
Results from these battery of tests all came back negative.
The fighters mentioned above were randomly selected. However, athletic commissions (or in this case the UFC) typically test the main event participants and fight night winners, as well as those who have failed drug tests in the past.
UFC 134 featured a main event rematch of a 2006 bout that saw Yushin Okami get gifted a disqualification victory over Anderson Silva. Five years later, "The Spider" got his revenge, destroying "Thunder" via second round knockout, extending his streak of victories inside the Octagon to 14 and streak of consecutive title defenses to nine.
That doesn't take away from "Shogun's" victory, as he looked as vicious as we've ever seen him.
