The only man with a win over Jon Jones is back.
Matt Hamill, who defeated Jones by disqualification in 2009, will take on Vinny Magalhaes in the main event of World Series of Fighting 20 on April 20 at Foxwoods Resort and Casino in Ledyard, Conn., the organization announced Thursday night.
Hamill (11-5) has not competed in MMA since falling to Thiago Silva at UFC Fight Night: Maia vs. Shields in October 2013. The 38-year-old former college wrestler, who was born deaf, announced his return and signing with WSOF last year. This bout with Magalhaes will be a semifinal in a tournament for the WSOF light heavyweight title. Silva takes on Ronny Markes in the other semi at WSOF 19 on March 28 in Phoenix.
Magalhaes (12-7, 1 NC) has won two in a row, most recently a fourth-round submission victory over Jason Brilz at Titan FC 30 last September. The win earned Magalhaes the Titan light heavyweight title. The 30-year-old Brazilian, a 10th Planet Jiu Jitsu black belt under Eddie Bravo, is a former UFC veteran and coach for Chael Sonnen on The Ultimate Fighter 17.
In the co-main event, Melvin Guillard will meet Ozzy Dugulubgov in a lightweight bout. Guillard (32-14-2, 2 NC), a UFC veteran, has missed weight his previous two bouts. He is 1-1 with WSOF, including a loss to lightweight champ Justin Gaethje last November. Dugulubgov (6-2), a 26-year-old prospect from New Jersey is coming off a knockout of Keon Caldwell last September.
WSOF 20 will air live on NBC Sports Network.
