World Series of Fighting (WSOF) 31: "Ivanov vs. Copeland" takes place June 17, 2016, at Foxwoods Resort Casino in Mashantucket, Conn. The main event on NBC Sports is Blagoy Ivanov (13-1) defending his heavyweight title versus Josh "Cuddly Bear" Copeland (13-1).
Having just announced a full set of preliminary matches that seemed to complete the card for June 17, WSOF surprised everyone with the announcement that middleweight fighter Phil Hawes (3-0) signed with the promotion and would fight Joshua Key (6-11, 2 NC).
Hawes has something in common with Jon "Bones" Jones: they both wrestled for Iowa Central Community College before starting their pro MMA careers.
