Boxing vs. MMA never die.
A couple of months ago, when Conor McGregor was theoretically retired from MMA and potentially pursuing other things as leverage for negotiations with the UFC, rumors flew that Floyd Mayweather and Conor McGregor were setting up a boxing match that would be one of the biggest fights in history. Then, McGregor came to terms with the UFC and was placed on UFC 202 in a rematch with Nate Diaz and those rumors cooled. Well now another former world champion boxer is throwing his name in the ring with McGregor.
