UFC 125 drug test results from NSAC for 'Resolution:' 14 pass, one fighter 'still being processed'

The Nevada State Athletic Commission (NSAC) today confirmed that 14 of the 15 competitors who were tested for illegal/banned substances after competing at UFC 125: "Resolution" on Jan. 1 have all passed with flying colors.
NSAC Executive Director Keith Kizer did not reveal the identity of the odd man out, saying only that Mr. X's urine sample is "still being processed."

Those who were screened for performance enhancers such as steroids and drugs of abuse like cocaine and marijuana, among others, and came back clean include main event participants Frankie Edgar and Gray Maynard, as well as Chris Leben, Brian Stann, Brandon Vera, Phil Baroni, Brad Tavares, Jeremy Stephens, Dustin Poirier, Diego Nunes, Daniel Roberts, Jacob Volkmann, Dong Hyun Kim and Clay Guida.

Vera was tested, however, his opponent, Thiago Silva, does not appear on this list.
It's possible that the Brazilian -- who was expected to fight Quinton Jackson at UFC 130 -- is still under the microscope, which would lend credibility to the reports that Rashad Evans has recently been contacted about a rematch with "Rampage."
It's important to reiterate that at this time, Silva has not been found guilty of any wrongdoing and nothing should be considered official until the NSAC concludes its testing.
Stay tuned.
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.
14 down, 1 to go.
