Nevada State Athletic Commission (NSAC) today confirmed that 13 of the 20 competitors who were tested for illegal/banned substances after competing at The Ultimate Fighter (TUF) 11 Finale on June 19 have all passed with flying colors.

Co main event participants Matt Hamill and Keith Jardine, as well as Court McGee, Kris McCray, Chris Leben, Aaron Simpson, Dennis Siver, 
Rich Attonito, 
John Gunderson, Brad Tavares, Kyle Noke, Chris Camozzi and Travis Browne were all screened for performance enhancers such as steroids and drugs of abuse like cocaine and marijuana, among others.

Results from these battery of tests all returned negative.

The fighters mentioned above were randomly selected. However, athletic commissions typically test the main event participants and fight night winners, as well as those who have failed drug tests in the past.

TUF 11 Finale featured a main event between the top two 185-pound fighters on TUF 11, Court McGee and Kris McCray.

"The Crusher" strangled the "Savage" in the second round to earn a "six-figure" contract with the promotion, as well as bragging rights as the show's latest winner.

Light heavyweight brawlers Jardine and Hamill -- who took home "Fight of the Night" -- went toe-to-toe for a blood-soaked three rounds, with "The Hammer" earning a close majority decision win from the ringside judges.
