As reported by MMA Junkie (mmajunkie.com) all fighter’s drug test came back clean. Ryan Bader, Antonio Rogerio Nogueira, Chris Lytle, Sean Sherk, Melvin Guillard, C.B. Dollaway, Matt Mitrione Frank Mir and Mirko Cro Cop all passed. All 9 fighters came clean for performance-enhancing drugs and tested negative for drugs of abuse (such as marijuana and cocaine). I am so glad these tests came back clean because I believe the UFC can’t afford another Chael Sonnen incident.
