RIO DE JANEIRO - All fighters who underwent drug testing at the recent UFC 152 and UFC on FUEL TV 5 events passed their drug tests.
Marc Ratner, the UFC's vice president of government and regulatory affairs, today confirmed the results with MMAjunkie.com.
Ratner said one fighter received a therapeutic-use exemption for testosterone-replacement therapy at UFC 152, but he wouldn't identify the individual, who tested within allowable limits, he said.Â
