Melvin Guillard (Esther Lin/MMA Fighting)Melvin Guillard Pulled from WSOF 20, Lucas Montoya Named Replacement Against Ozzy Dugulubgov José Youngs April 7, 2015 News, Spotlight, WSOF Earlier this week World Series of Fighting announced that it has pulled Melvin Guillard from his scheduled WSOF 20 co-main event matchup with Ozzy Dugulubgov after failing to deliver his required medical results by the April 6 deadline. As a result of Guillard’s disappearance, the promotion has replaced him with the streaking Lucas Montoya, who was originally slated for preliminary card action. “We are disappointed that we are in a position where we have to pull Melvin from this event but, given the fact that he did not turn in his required medical exam results by this morning’s deadline, we were left with no other choice but to do so,” stated WSOF President Ray Sefo. “Melvin and his camp were reminded more than once about the hard deadline. Yet they failed to deliver what was necessary in order for him to compete.” Montoya (8-3) of Layton, Utah will enter the cage on a four-fight win streak, with three of the four victories having come by way of TKO or submission. His opponent, Dugulubgov (6-2) is looking for his second straight win after delivering a thunderous KO (punch) on Keon Caldwell at WSOF 13 on Sept. 13, 2014. The lightweight matchup between Nick Newell (11-1) and Joe Condon (12-7) has also been named the new WSOF 20 co-main event. Montoya’s original opponent, Abdula Dadaev, will no longer compete on the card, but will receive his fight purse. WSOF 20 is expected to air on April 10 liveF from oxwoods Resort Casino in Mashantucket, Conn. In the main event, David Branch (15-3) and Ronny Markes (15-3) will collide in a contest that represents the second matchup in the WSOF multi-event tournament that will crown its winner the inaugural WSOF world light heavyweight champion.
