Increasingly it looks like World Series of Fighting and Melvin Guillard could be splitting ways, as the promotion has reportedly yanked the UFC vet from its card this Friday.

Guillard was scheduled to fight Ozzy Dugulbgov at WSOF 20 on April 10th, but the promotion’s president, Ray Sefo, recently told MMA that they haven’t received the fighter’s medicals. Sefo also claims that none of the promotion’s attempts to reach Guillard regarding the matter, or to promote Friday’s card, have been returned. As a result, Guillard has been pulled from the event, and now Lucas Montaya will face Ozzy Dugulbgov.

Now, if you heard Guillard on Submission Radio recently, this news likely isn’t terribly shocking. According to a follow up report from Bloody, Guillard relayed on the show that he isn’t too happy with WSOF, since according to him, he was promised a fight this past February. The last time Guillard fought was in November, when he was handed a split decision loss by the promotion’s lightweight champ, Justin Gaethje.

Guillard came in over weight for the bout, however, so the contest was a non-title fight. He was also fined 50% of his purse, since he failed to make weight for his WSOF debut in July, when he TKO’d Gesias “JZ” Cavalcante. Here is some of what Guillard had to say regarding his issues with WSOF and his loss to Gaethje:

“I’m the better athlete, you know what I mean? I just wasn’t in the best shape I should have been in. I had trouble making weight. So all those things played a factor, and then when I missed weight and I wasn’t fighting for the title, I was already mentally beat anyway. You know what I mean? And on top of that, I let them take 50 percent of my purse. So technically speaking I shouldn’t have even gotten in the ring, but on top of that, you know after I agreed to take the fight, Ali [Abdelaziz] the promoter for World Series, he promised me a fight like a lot sooner. I was supposed to fight in February and then he kind of reneged on that.”

The 32 year-old also noted that he’d rather fight in the UFC, and take on top ten contenders, than be a champion with WSOF…

So, one would think that Guillard could be looking for a new promotional home soon, but we’ll see what happens.
