I think Dana White should make this fight happen under modified MMA rules. Three round fight. Round 1 is boxing rules only (which I think Cain may actually do quite well). Round 2 is Unified MMA Rules, then Round 3 is boxing only again. I think this fight would be exciting and would test the urgency of Fury to knock out Cain in the first round given that Round 2 is MMA rules. I actually think Fury would have a hard time punching and getting used to MMA gloves after switching from boxing style gloves.
