Current Maximum Fighting Championships Middleweight Champion Elvis Mutapcic has signed a five fight deal with the World Series Of Fighting. Mutapcic will now vacate the championship and it will be deemed vacant until MFC officials crown a new champion. Thus far in his five plus year MMA career, Mutapcic has fought the likes of Zak Cummings, Artenas Young, Joseph Henle and Sam Alvey. No official date has been set yet for the WSOF debut for Mutapcic, but it could come as early as this June.
