Ray Sefo recently announced he’s temporarily stepping down as president of the World Series of Fighting promotion, and ahead of his WSOF 4 fight, he’ll join the WSOF Fan Fest on Saturday. Officials recently announced details for the one-day fan event, which takes place at Dave & Buster’s (4821 Mills Circle) in Ontario, Calif., from noon to 4 p.m. PT. Ontario also plays host to WSOF on Aug. 10, where Sefo (2-1), a veteran kickboxer and boxer who’s also dabbled in MMA, meets fellow heavyweight Dave Huckaba (20-5) in an NBC Sports Network-televised main-card bout. The 42-year-old Sefo, who competes professionally for the 88th time in combat sports, stepped down as WSOF president so he can concentrate fully on his bout. “I’m looking forward to another chance to step into the cage, but before I do, I felt taking a temporary leave from my executive duties was the right thing to do,” Sefo stated earlier this week
