The Nevada State Athletic Commission (NSAC) tested 10 fighters on the UFC 74: "Respect" fight card for illegal anabolic substances such as steroids, as well as stimulants, and all of them passed, according to FightNetwork.com.

UFC Heavyweight Champion Randy Couture, Gabriel Gonzaga, Georges St. Pierre, Josh Koscheck, Roger Huerta, Alberto Crane, Kendall Grove, Patrick Cote, Frank Mir and Antoni Hardonk were all clean for the August 25 pay-per-view (PPV) event from the Mandalay Bay Events Center in Las Vegas, Nevada.

The NSAC is still waiting to hear word on results for "drugs of abuse," according to the report.

This is good news for the UFC -- as well as the sport of mixed martial arts -- which took a beating after UFC Lightweight Champion Sean Sherk and his opponent at UFC 73: "Stacked," Hermes Franca, both tested positive for steroids following their championship bout.

Franca owned up to the charge, while Sherk is still awaiting to appeal the finding before the California State Athletic Commission (CSAC) sometime in October.
