Former Ultimate Fighting Championship light heavyweight titleholder Tito Ortiz was the latest mixed martial artist drug tested under the Nevada State Athletic Commission’s new out-of-competition testing procedure. According to NSAC executive director Keith Kizer, Ortiz’s test results were negative.

Kizer indicated that the commission also intends to test Ortiz’s opponent, Lyoto Machida.

B.J. Penn and Sean Sherk were reportedly the first mixed martial artists tested under the new policy. Also tested were boxers Shane Mosley and Zab Judah. All four fighters tested clean.

Ortiz and Machida face each other as part of the undercard of UFC 84 on May 24. Current UFC lightweight champion Penn defends against former champion Sherk in the evening’s main event.
