The World Series Of Fighting has released UFC veteran Melvin Guillard, who went 1-1-0 during his time in the promotion. Guillard made his promotional debut by defeating Gesias Cavalcante at the WSOF 11, but then lost to current WSOF Lightweight Champion Justin Gaethje at the WSOF 15 (a bout that Guillard missed weight). Guillard then requested his release from the promotion after getting pulled from a fight against Ozzy Dugulubgov at the WSOF 20 because Guillard failed to turn in his medical paperwork to the promotion.
