Lightweight opponents Sean Sherk and Frank Edgar and welterweight rivals Matt Serra and Matt Hughes have all tested clean in drug tests administered by the Nevada State Athletic Commission ahead of UFC 98, which takes place on May 23rd in Las Vegas.
NSAC executive director Keith Kizer today confirmed the results to MMAFrenzy.com via email.
The tests were part of the NSAC’s in-training drug testing, which tests fighters before an event, instead of only on event night, to reduce the possibility of fighters cycling off performance enhancing drugs and avoiding detection. Though any fighter can be tested under the policy, headliners and past offenders are most commonly required to undergo the tests.
