Walking Haye down across the ring, it was Bellew who took control as Haye looked increasingly troubled.
Haye appeared to injure his right leg again, just as he did in the first stoppage loss, although he dismissed questions about his fitness. Haye, on the other hand, will have to evaluate his choices as to fight on or not. For now, it's Haye vs. Bellew 2, which should be thoroughly entertaining no matter who has his hands raised after the final bell.
Bellew, 35, dedicated the fight to his late brother-in-law, Ashley Roberts.
Before the first matchup against Bellew, Haye made his return to boxing with a couple really easy fights against Mark de Mori (first-round TKO) and Arnold Gjergjaj (second-round TKO), something he now admits was a mistake.
In the third round, Bellew twice sent Haye to the canvas thanks to a pair of powerful right-hand punches.
Tony Bellew knew the fight was his to lose in the third round.
Bellew tried to force the finish in the fourth, hammering in hooks and right hands as Haye stumbled gingerly around the ring.
David Haye: "Bellew fought a very good fight and I didn't, simply".
Havasu horse bettors ready for Kentucky Derby
With $2 million on the line for a Derby-winning horse, there's even more to be made for the guys who know their stuff. NOLA.com's Jeff Duncan is buying Audible as his Kentucky Derby favorite and the lead horse in his projected trifecta.
The sibling of his long-term partner Rachel reportedly plunged from a balcony during a family holiday in Cancun a year ago and the fighter says it "destroyed him".
No, I'm fully healthy, he said.
Tony Bellew repeated his victory over David Haye in their heavyweight rematch as he stopped his British rival in the fifth round.
"I don't know", admitted Haye. Haye was seeking to take back the pace of the fight with his jab, however, he was still getting countered by the now patient Bellew.
"I'm a clever man, I have brains, I have skills". Bellew, who like Haye is a former world cruiserweight champion now operating at heavyweight, is ranked No. 7 with the WBC, and there is no obvious next opponent for him. Aged now 37, Haye has nothing to prove as a fighter after a successful and glamorous career in the sport.
Haye will have to have a long think about where his career can go from here, but as for the Bomber, he wants a title shot next, and Eddie Hearn will need to deliver for his new golden boy.
This time there was no injury to blame, but Haye was already going back on his own word that he would quit not only if he was beat, but even if he won and didn't impress.
"What about Andre Ward, pound-for-pound king?"
