Nevada Athletic Commission: All Fighters Test Clean at UFC 148

---

The Nevada Athletic Commission on Friday announced that all 22 fighters who competed at UFC 148 tested negative for prohibited substances.

NAC Executive Director Keith Kizer informed Sherdog.com of the test results via email. UFC 148 took place July 7 at the MGM Grand Garden Arena in Las Vegas and was headlined by a long-awaited middleweight title rematch between reigning champion Anderson Silva and challenger Chael Sonnen. Nevada tests fighters for both performance-enhancing drugs and drugs of abuse.

Silva successfully defended his belt for a 10th straight time at the event, surviving a strong first round from Sonnen and then delivering a technical knockout finish in the second frame. Sonnen -- who was previously suspended in California after producing an elevated testosterone-to-epitestosterone ratio following his first fight with “The Spider” in 2010 -- was granted a therapeutic use exemption for testosterone prior to receiving a license in Nevada under the conditions that he adhere to dosage restrictions in the days leading up to the event and then submit to a post-fight blood test the morning after his bout.

The pay-per-view card also saw former light heavyweight champions Forrest Griffin and Tito Ortiz do battle, with Griffin earning a unanimous verdict to take the deciding bout in their three-fight series. Meanwhile, ex- Strikeforce middleweight titlist Cung Le earned the first Octagon win of his career, as the san shou kickboxing stylist topped returning Canadian Patrick Cote. Additionally, former middleweight title contender Demian Maia impressed in his welterweight debut, injuring judo practitioner Dong Hyun Kim during a takedown attempt just 47 seconds into their bout.
