Justin Gaethje Undefeated WSOF lightweight champ Justin Gaethje (16-0) will likely meet six-time WSOF veteran Ozzy Dugulubgov (8-2) in his next title defense. WSOF President Ray Sefo recently revealed the plan on WSOF.com . “We’re still working out the details, but right now, I’m leaning toward going with Ozzy Dugulubgov for that shot,” Sefo wrote. “Ozzy debuted with us back in 2013, on just our second event. He’s gone 5-1 in his six World Series of Fighting appearances, and that one loss came via split decision.
