On Monday, the Nevada State Athletic Commission released the post-fight drug test results for the fighters of UFC 98, held May 23 at the MGM Grand Garden Arena in Las Vegas.

Ten fighters were tested for performance enhancers and drugs of abuse following their bouts: Lyoto Machida, Rashad Evans, Matt Hughes, Chael Sonnen, Frank Edgar, Brock Larson, Kyle Bradley, Krzysztof Soszynski, Yoshiyuki Yoshida, and George Roop.

All fighters came back negative.

The event saw the light heavyweight title change hands once again when Lyoto Machida knocked out Rashad Evans in the second round. Machida is expected to return in October or November. Evans will fight again in December against Quinton “Rampage” Jackson after they conclude a stint as rival coaches on The Ultimate Fighter: The Heavyweights.

So far, 2009 has been a quiet year for the Las Vegas-based promotion. Karo Parisyan remains the sole fighter to be flagged by the NSAC for illicit drug use. The Armenian-born fighter remains suspended until January of 2010.
