Vitor Belfort has dropped out of his upcoming UFC middleweight title shot a few hours after the Nevada Athletic Commission banned testosterone replacement therapy.
Belfort was scheduled to fight 185-pound champion Chris Weidman in Las Vegas at UFC 173 on May 24. His title shot was given to Lyoto Machida on Thursday night.
The 36-year-old Belfort has been open about his use of synthetic testosterone for a few years. The former light heavyweight champion's sanctioned steroid use has coincided with an improbable career resurgence for three consecutive early round knockout victories in 2013.
The influential Nevada commission voted unanimously on Thursday to stop granting therapeutic use exemptions for TRT, closing a widely criticized loophole that allowed fighters to compete on steroids.Belfort says he'll continue fighting, but without TRT.
