Yesterday the UFC 146 press conference, the Nevada State Athletic Commission (NSAC) decided to ‘surprise’ some of the fighters with a drug test right then and there.

Keith Kizer stated that it was the first time the NSAC screened several participants of an MMA event during a scheduled press conference, that was so far ahead of time, (the event is in late May.)

“We brought the drug test to them instead of making them go to the drug test,” Kizer said. “If they were not in Las Vegas, I would need to find them a lab, which is of course, much more of a hassle.”

The six fighters tested included UFC heavyweight champ Junior Dos Santos, his opponent Alistair Overeem, former champs, Frank Mir and Cain Velasquez, as well as Roy Nelson and Antonio Silva.

This test counts as one of the random tests Overeem must undergo after his hearing this past December.

Kizer stated that the NSAC has a deal in place with Quest Diagnostics, in which testers are sent on site to obtain blood samples. At the end of the UFC 146 presser, fighters were taken in groups of two to be tested.

The results of these tests will not be made available to the public until after UFC 146, unless one of the tests comes back positive of course.
