No official source, bt firstly Calzaghe apparently offered Glen johnson a shot at 168, when Johnson said he couldnt make the weight, Johnson came back with a catch weight not to sure at what weight, but Calzaghe and his team declined, i read this on Hatton's forum, i dont understand Joe and his team?? Why wouldnt he take this fight if he is seriously looking at Tarver in the fall?? This is a perfect fight at 175 to see exactly where he stands, but again Franky and Joe fail to deliver.
