From MMAJunkie.com:
Six UFC 91 fighters, including the event's headliners, have passed pre-event drug tests administered by the Nevada State Athletic Commission.
The commission recently enacted year-round drug testing, and the NSAC has been testing fighters approximately a month before fight time.
In an email sent to MMAjunkie.com (www.mmajunkie.com), NSAC Executive Director Keith Kizer confirmed main-event fighters Randy Couture and Brock Lesnar were tested, as were undercard fighters Amir Sadollah, Nick Catone, Jorge Gurgel and Aaron Riley.
