He might aswell, he's been a colossal disapointment. Showed early promise, a couple of good wins in 2007 and bugger all since.
He is likely the WBA mandatory and is waiting for the winner of that before deciding what to do. Atlas has already said he wants a fight with Haye.
If both were sharp and at the top of their game it would be. Povetkin has been injured, psychologically destroyed by Atlas and looking non-impressive against C-level opp. Chagaev hasn't done much better, if at all. I think this fight will be lousy and whoever gets the belt won't defend it long if at all.
Supposedly the event actives the Atlas crystals and he gets to ask the dragon Shenron for three wishes.
