The Nevada State Athletic Commission approved Frank Mir for testosterone-replacement therapy in advance of his title fight with heavyweight champ Junior Dos Santos at UFC 146.
Mir is the fourth athlete to get a therapeutic-use exemption, NSAC Executive Director Keith Kizer today told MMAjunkie.com.
Middleweight title contender Chael Sonnen, who is currently taking steps needed to gain approval, is expected to be No. 5 in advance of his title fight with champ Anderson Silva at UFC 148.
