Fact Check: World Series of Fighting 33

Ozzy Dugulubgov believes he has the blueprint he needs to succeed where all others before him have failed.

Dugulubgov will challenge the undefeated Justin Gaethje for the World Series of Fighting lightweight championship in the WSOF 33 main event on Friday at the Municipal Auditorium Arena in Kansas City, Missouri. In the five-round co-headliner, David Branch puts his light heavyweight crown on the line against “The Ultimate Fighter 8” finalist Vinny Magalhaes.

The rest of the six-fight main card features a welterweight clash matching former Ring of Combat champion John Howard with Abubakar Nurmagomedov, a heavyweight scrap pitting Ultimate Fighting Championship castaway Shawn Jordan against Ashley Gooch and a pair of lightweight tilts, as American Top Team’s Jason High meets Joao Zeferino and Luiz Firmino faces Brian Foster.
