Haye had better worry about sparking out Man mammoth firstly and had his chance to mix it up with Wlad...but hurt his chest,I mean his back.Valuev is terrible,but is half a foot and 80-100 lbs of terrible that Haye has never shared a ring with.For a guy with past stamina issues and only 1 fight in the past one and a half years,thats nothing to take lightly.
