Melvin Guillard’s most recent appearance for World Series of Fighting was a lightweight championship match vs. Justin Gaethje.

But if “The Young Assassin” has his way, it will also be his last.

Guillard, appearing on Submission Radio recently, discussed his issues with the promotion and those that run it.

“I’m on my way out the door from World Series most likely,” he 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.”

The former UFC fighter was fined for missing weight vs. Gaethje in November. He lost via split decision, dropping his overall record to 32-14-2.

“Ali (Abdelaziz, WSOF official) didn’t man up and follow his promise, and you know right now, it’s a little bit personal to me,” Guillard said. “I’m going to let them know how I feel, for when you (expletive) over Melvin Guillard and not give him what he asked for after he swallows his pride and takes a fight and let’s them take 50-percent.”

Guillard’s last UFC fight came in 2014 when he fell via decision to Michael Johnson. Overall, he’s gone 2-4 with one no-contest since 2012, including losses to Donald Cerrone and Jamie Varner.

“To be honest, instead of being the World Series of Fighting champion, I’d rather be in the UFC just fighting in the Top-10 and probably never becoming the UFC world champion; if I had that option,” he said. “Sometimes I tear up watching that (the UFC). And the sad part I think about was how they released me.”
