So since Jones-Calzaghe are fighting for a clear supremacy at LHW division there is clear possibility Jones wins and gains ring LHW title. But since Calzaghe still posses the ring MW title which is not on the table in the first fight then depends whether the fight will be close it is possibility for the immediate rematch and even trilogy .... great future for both divisions I think :smoke
I doubt if there is a return match, especially if RJJ wins a tough match. I was suprised that he gave an initial rematch to tarver after defeating him the first time.
Fighting Calzaghe is a dream fight for RJJ, it's guarunteed that he will not be knocked out so he knows even if he loses he can go out with his pride intact
It seems obvious to me that after RJJ, Joe is going to have a farewell fight in Cardiff in front of 90,000 people against Pavlik. I would be very surprised if this didn't happen.
