The Nevada State Athletic Commission said that at least one competitor from UFC 143 has tested positive for a banned substance.
In an email sent today to MMAjunkie.com, NSAC
Executive Director Keith Kizer did not specify whether the positive test
was for drugs of abuse or performance-enhancing drugs but said a
release was forthcoming today.
"I am still waiting for all the steroid and drug test results to come back," Kizer stated.
