"I'm not injured. I'm fully healthy", said Haye, who refused to say whether he will retire.
Promoter Eddie Hearn will try to tempt American pound-for-pound star Andre Ward out of retirement and to step up to cruiserweight for a fight in the United Kingdom later this year as one option for Bellew.
Bellew continued to dominate, and in round five, Bellew another massive left hook that sent Haye to the deck for a third time.
But it was a sweet left uppercut that really finished it in the fifth as Bellew dropped him again with the shot he said he learned from ring greats Felix Trinidad and Joe Frazier.
Victory will once and for all put this rivalry to bed with Bellew proving his first victory over Haye last March was no fluke.

It was the ex-world heavyweight and cruiserweight champion's second loss to fellow Briton Bellew, 35, in 14 months.

Opposite him, a confident and self assured Tony Bellew found his range and stuck to a smart game-plan once again, effectively using his lead hand to measure and his feet to adjust his distance.
James Buckley, who played Jay in popular TV programme The Inbetweeners, interrupted the press conference mock Haye's promoter Adam Moralee.

Bellew and Haye continue to throw the jab. Rodriguez, who scored two knockdowns, won every round on two of the scorecards and 10 rounds on the other. David looked very unstable at times but was more than willing to fight on.
Here's the full Haye vs Bellew undercard, in reverse order. Haye was fighting on instinct and was willing to fight fire with fire whilst trying to stay out of range and counter the work of Bellew.
