I think it could happen. Vargas was supposed to have a come back fight against Henry Buchanan on April 16th, but Vargas got really sick and the fight's been pushed back. Obviously he must be returning for something bigger.
Interesting except I can't see that one going much difference then their second MMA fight. Their second MMA fight was almost all standing and had very little kicks, it was almost a boxing match and Diaz won that one.
I think Diaz just wants to be paid that boxing money and I myself would not mind seeing him take a shot at it and see where it can take him.
