UFC on FOX 1 drug test results come back clean for 'Velasquez vs Dos Santos' on Nov. 12 in Anaheim

UFC on Fox 1 drug test results are in from the California State Athletic Commission (CSAC), who today confirmed (via Sherdog.com) that 14 fighters tested for illegal/banned substances after competing at UFC on Fox 1: "Velasquez vs. Dos Santos" on Nov. 12 have all passed with flying colors.

Main event participants Cain Velasquez and Junior dos Santos as well as Ben Henderson, Clay Guida, Ricardo Lamas, Clay Harvison, Cub Swanson, Mackens Semerzier, DaMarques Johnson, Robert Peralta, Aaron Rosa, Pablo Garza, Matt Lucas, and Dustin Poirier 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.

"Velasquez vs. Dos Santos" featured Brazilian bomber, Junior dos Santos, doing what he does best by knocking out Cain Velasquez. Except this time, the victory earned him the UFC heavyweight championship.

That may have been the only bout to make the FOX airwaves but it's not the only fight that happened that night.

No, Ben Henderson turned in yet another masterful performance in taking a unanimous decision victory over Clay Guida, which earned "Bendo" a 155-pound title shot.

But don't take my word for it.
