Sean Sherk Tests Clean in Nevada Drug Testing

Former Ultimate Fighting Championship lightweight titleholder Sean Sherk was randomly drug tested under the Nevada State Athletic Commission’s new out-of-competition testing program. His results came back negative for steroids and recreational drugs, according to a report on

The new policy is geared to deter fighters from “cycling,” by randomly testing licensed competitors throughout the year.

“Random testing throughout the year will further deter any fighters considering taking non-approved substances,” said NSAC executive director Keith Kizer. “The additional testing, which will be paid for by the Commission, will help us keep the sport of unarmed combat safe and fair for all fighters.”

Sherk tested positive for the steroid Nandrolone following his first title defense against Hermes Franca at UFC 73 in July of 2007. He was released from suspension by the California State Athletic Commission on April 14 after meeting all of the requirements outlined by the commission.

Since the institution of the new testing program, four fighters have been tested: B.J. Penn, Sean Sherk, Shane Mosley and Zab Judah. All four fighters results came back clean.
