No, but i think it will happen because fighting each other gives them the biggest pay day available. It's about money.
3 great fights, only 1 point separates them. On one hand these two little guys deserve a good purse after what they have shown us and their best option is against each other. On the other hand you have the amount of damage they have done to each other and its already 2-1, even though its hella close. I will not mind if Izzy and Rafa never fight against each other again, but if they do fight I'm right there at the edge of my seat waiting for the good fight.
Like I said in the other thread, these guys can fight each other 20 times, seeing these two fight each other never gets old.
