Bellator has been doing regular co-promoted events and fighter exchanges with Rizin for years, but they’ll raise the bar New Year’s Eve. The two promotions announced Monday a Bellator vs. Rizin event for Dec. 31 that will see fighters from each fight each other against all five fights on the main card. Included in that mix will be a current Bellator champion and at least three former champions: Patricio Freire , A.J. McKee , Juan Archuleta and Kyoji Horiguchi
