The Nevada State Athletic Commission (NSAC) today issued the results of the drug tests performed prior to UFC 84: "Ill Will" at the MGM Grand Garden Arena on May 24, revealing that all 15 fighters who were screened for banned substances tested negative.

BJ Penn, Sean Sherk, Keith Jardine, Wanderlei Silva, Tito Ortiz, Lyoto Machida, Rousimar Palhares, Ivan Salaverry, Rameau Thierry Sokoudjou Sokoudjou, Rich Clementi, Yoshiyuki Yoshida, Shane Carwin, Thiago Silva, Foran Reljic and Dong Hyun Kim were all among the fighters who were randomly selected to provide samples before their fights.

The tests are designed to deter fighters from ingesting performance enhancing drugs such as steroids and stimulants, as well drugs of abuse like marijuana, heroin, etc.

NSAC has adopted a new year-round drug-testing policy, which is perhaps the strictest of its kind in the sport.

In fact, the NSAC also tested Sherk, Penn and Ortiz weeks out from the pay-per-view (PPV) event to ensure that fighters don't "cycle" off of substances prior to their tests.

The tests were random -- there was no other reason the fighters mentioned above we singled out.

However, Sherk has tested positive for steroids in the past and Keith Kizer, NSAC executive director, has mentioned that previous failed tests will be a factor (among others) when it comes to deciding if a fighter should or should not be tested.
