Cro Cop was expected to fight Satoshi Ishii in a rematch on 31 December 2014 for the IGF Championship. However, the rematch was canceled due to a rib injury sustained by Ishii. Cro Cop stayed on the card and a new match up was being sought for a brief period. On 1 December, it was reported that Ishii would be able to heal up in time to take the fight, and the rematch was official once again. Cro Cop defeated Ishii via TKO, landing a head kick and follow up punches just as the second round was coming to a close. Ishii was unable to make it to his corner under his own power, forcing the referee to call an end to the fight. Following his return to UFC, Cro Cop was stripped of the IGF Championship on 23 January 2015.
