Six fighters scheduled to compete at UFC 91 in Las Vegas on November 15 have all passed preliminary drug tests, according to Nevada State Athletic Commission Executive Director Keith Kizer.

Headliners Randy Couture and Brock Lesnar were tested by the NSAC, along with Nick Catone, Amir Sadollah, Aaron Riley and Jorge Gurgel.

Earlier this year, Nevada became one of the first states to approve random drug screenings prior to an event rather than testing after the conclusion of a fighters bout, which has traditionally been the case.
