Yep, I bet harrison has been training since he heard the possibility over a month ago

Harrison does have stamina for a man his size, whereas Haye has had to plod to last a distance. Im actually looking forward to it. At least with Harrison we have a genuine puncher against Hayes week chin, unlike Ruiz and Valuev (who can both punch but Harrisons punches have to be regarded as more of a threat).

Harrison is 6,5", and a southpaw with a bit of skill, stamina and power. This could well be a nightmare for Haye.
