Jirov throws a lot. He would come out throwing a lot hard at Haye, and Hayes chin is pretty bad. Haye may drop him with a right hand, but ultimatly i think Jirov by TKO.
I think Jirov's workrate and power would be too much for Haye although I think Haye would have his moments by countering in between Jirov's punches but ultimately I think Jirov knocks Haye out.
