World Series of fighting returns this week with a very solid top to bottom card. WSOF 33 is headlined by a pair of title fights as Justin Gaethje defends his lightweight belt against Ozzy Dugulubgov and Dave Branch puts the light heavyweight title on the line against Vinny Magalhaes. Throw in Jason High, Joao Zeferino, Brian Foster, and Abubakar Nurmagomedov and you've got a solid main card. Toss a bunch of Russian prospects on the prelims and you've got one of the best WSOF cards in a long time.
