UFC Fight Night 32 will feature the first MMA fight between athletes on testosterone-replacement therapy.

Vitor Belfort and Dan Henderson, who meet on Nov. 9 in Goiania, Brazil, were granted the TRT exemptions for their light heavyweight contest for the main event. Brazilian MMA Athletic Commission’s (CABMMA) medical director, Dr. Marcio Tannure, told MMAFighting.com their exams were approved by the commission.

MMAJunkie first reported the news.

"They were already on treatment," Dr. Tannure told MMAFighting.com, "and CABMMA approved their exams to continue the treatment for this fight."

According to Dr. Tannure, Belfort and Henderson are the only fighters on the card who required for an exemption to use the testosterone therapy.

Belfort enters the cage after consecutive knockout victories over Michael Bisping and Luke Rockhold in Brazil, while Henderson looks to get back to the win column following back-to-back split-decision losses to Rashad Evans and Lyoto Machida.
