MANILA, Philippines – Mixed martial arts (MMA) fighter Chael Sonnen said he will abide by the recent ruling of the Nevada State Athletic Commission (NSAC) which voted unanimously to ban the use of testosterone replacement therapy (TRT) in the state.
Sonnen is one of several MMA fighters who are known to use TRT in the past.
"The rules are the rules," he said in a Yahoo! Sports report. "Yesterday, it was legal; so quit complaining. Today, it’s illegal; so quit complaining. Testosterone is out."
The NSAC’s decision has forced Vitor Belfort, another TRT user, to withdraw from his middleweight title challenge against UFC champion Chris Weidman.
Belfort was supposed to fight Weidman on May 24 but due to time constraints relating to his testosterone therapy, he has decided to bail out from the fight.
"As other jurisdictions may follow suit, I am going to drop my TRT program and compete in MMA without it," Belfort said. "Given the time constraints involved between now and my proposed next bout in May, I have determined not to apply for a license to fight in Nevada at this time."
Weidman will instead fight former light heavyweight champion Lyoto Machida.
