Following a three-month dry spell in which no mixed martial artists were tested under the Nevada State Athletic Commission's new out-of-competition drug testing process, there have been a number of athletes from the upcoming UFC 91 fight card tested recently.

NSAC Executive Director Keith Kizer notified MMAWeekly.com on Monday that Mark Bocek and Alvin Robinson are the latest fighters to be scrutinized under the state's out-of-competition testing process. Both fighters returned negative test results.

Bocek and Robinson -- who face each other on Nov. 15 -- bring the number of fighters tested from the UFC 91 fight card to eight. Never before has the commission tested that number of athletes from one fight card, whether it be for mixed martial arts or boxing.

The other six UFC 91 fighters that have already been tested include main eventers Randy Couture and Brock Lesnar, as well as Nick Catone, Amir Sadollah, Aaron Riley and Jorge Gurgel. All of them also tested negative.

In reference to the varying number of athletes tested at various points throughout the year, Kizer recently told MMAWeekly.com, "We will not set any pattern ... kind of defeats the purpose."
