Floyd is not going to seriously fight in MMA, whoever believes that is simply gullible. He said he was getting into it, and i'm pretty sure its a promotional venture with his buddy Mark Cuban.

Why would he leave a sport that pays him millions to dominate for a sport that only gives their top fighters a fraction of that money and where he'll be outgunned?

If he did fight inside a cage, it'd be a simple exhibition bout against a horrible opponent that will probably be instructed to make Floyd look good.
