Boxing star Andre Berto talks some nonsense about having talked to Dana White about a stint in the UFC. Berto also says that his little sister is going to try out for the upcoming season of The Ultimate fighter.Link
His father and his brother were both MMA fighters and Berto seems to have hit the wall as far as his boxing potential goes, so it's not out of the question.
He has a good build and athleticism for MMA but how successful he would be probably has a lot to do with how much non-boxing training he did with his family. He was an Olympic boxer so he must have focused his training on boxing at some point when he was fairly young.
