What is MMA? Is it like Ultimate Fighting or WWE? If it is similar to the UFC, I think a boxer like Tyson would get killed. He would be deadly from the outside, but once his opponent got his hands on him and started grappling, that would be the end of it.

I always thought Tyson would try a boxing comeback or work for the WWE. He was supposed to do a guest referee/fake fight at a Wrestlemania, but he lost to Buster Douglas in Tokyo, and Douglas took the gig.
