Just four days from a planned bout with Ozzy Dugulubgov at WSOF 20, Melvin Guillard has been pulled from Friday’s fight card.

MMAjunkie was today told “The Young Assassin” will not compete at WSOF 20 because WSOF executives have been unable to reach Guillard in the days ahead of the contest.

“Obviously, we would have liked to have seen Melvin compete at this weekend’s event,” WSOF President Ray Sefo told MMAjunkie. “But it’s Monday, four days away from the fight, and we don’t have his medicals, nor have we heard from him. He has not responded to any of requests from our PR team to help promote the show, and we alerted his management team that if we did not receive his medicals by 10 a.m. today, we would have no choice but to pull him from the card, and unfortunately, that’s what we’ve been forced to do.”

With Guillard (32-14-2) scrapped from the event, Lucas Montoya (8-3) moves up from a planned preliminary-card contest and faces lightweight Dugulubgov (6-2). A lightweight bout between Nick Newell (11-1) and Joe Condon (12-7) has been elevated to co-main-event status.

Featuring a light-heavyweight tournament bout between Dave Branch and Ronny Markes, WSOF 20 takes place at Foxwoods Resort Casino in Mashantucket, Conn. The five-fight main card airs on NBCSN following prelims on MMAjunkie.

WSOF’s decision comes on the heels of a scathing interview Guillard recently gave to Submission Radio Australia, in which the veteran slugger admitted he didn’t see much of a future in the promotion.

“I’m on my way out the door from World Series most likely,” Guillard said. “I might even pit stop in Bellator because right now Bellator, from what I’m seeing, I hear they’re taking care of their guys and they’re paying the guys pretty decent.”

Guillard’s time under the WSOF banner was tumultuous, at best. In two appearances for the promotion, he failed to make weight both times, including a November bout with Justin Gaethje that was expected to be for the promotion’s lightweight belt. It was changed to a non-title affair after Guillard’s struggle at the scale.

“With Melvin missing weight in his two previous WSOF bouts, not hearing from him this close to the fight gives us serious concerns as to whether or not he would make weight for this fight either,” Sefo said. “But ultimately, we’re really in a bind because he hasn’t turned in his medicals yet, and that becomes an issue with the commission. So we’re not even sure he’d be able to fight. With all that in mind, we decided we had to make a move today to protect our event.”

Sefo wouldn’t say if Guillard will be booked again at a later date.
