The Merseysider floored Haye twice in the third round and the fight was waved off in the fifth after the 37-year-old toppled to the canvas again, with Bellew producing a second successive stoppage victory at The O2.
Haye appeared to injure his troublesome right leg, just as he did in their first fight, and will be forced to consider retirement, but Bellew can look ahead to more major fights either at heavyweight or cruiserweight.
