Nothing is scheduled at this time, but the expectation is that sometime in the not too distant future, the UFC will book middleweight champion Chris Weidman to face No. 2 ranked contender Vitor Belfort. When that fight is booked, Belfort intends to apply for a therapeutic use exemption (TUE) for testosterone replacement therapy (TRT).

This news, broken by Ariel Helwani on UFC Tonight, contradicts Belfort's manager Glenn Robinson. Robinson appeared on Helwani's show, The MMA Hour earlier this week and said that although he had not discussed the subject with Belfort, he did not believe the fighter would apply for a TUE for the Weidman fight.

On Wednesday's UFC Tonight, Helwani said that he had spoken to Belfort and, "He said he's on TRT and that his doctors said he has to be on it. This has been prescribed and he's planning on applying to be on a TUE for the next fight."

The fly in the ointment in all of this is that UFC CEO Lorenzo Fertitta said the promotion has plans to book the Weidman versus Belfort fight in Las Vegas, a city where Belfort has failed a drug test for performance enhancing drugs in the past. Specifically, Belfort tested positive for 4-hydroxytestosterone in October 2006. The positive test came after Belfort dropped a decision to Dan Henderson at Pride 32. The positive test resulted in a nine-month suspension.

Keith Kizer, who will serve as Nevada State Athletic Commission executive director until January 27 when he officially steps down from that position, said of Belfort in March 2013, "I don't see Vitor Belfort getting a TRT exemption from us" due to the failed drug test.

The NSAC is searching for a replacement for Kizer, and it is likely that his replacement will be the one involved in working out the details of Belfort's application for a TUE.

The UFC is waiting on the results of an MRI on Weidman's knee before they book him to face Belfort.
