On Saturday night, David Haye's career was left in ruins after he again lost to Tony Bellew, this time after a fifth-round stoppage in their rematch at London's O2 Arena.

At 37 and having proved increasingly injury prone, Haye's reputation has been left beyond repair after successive defeats by an opponent who was a light-heavyweight, while he reigned as the WBA heavyweight champion at his peak.

Bellew, 35, is not a true heavyweight, and while struggling until landing the fight-changing right hand that put Haye down in the third, he then exposed his rival as shot.

Haye is refusing to rule out the possibility of fighting again.

He wants to review the tape of his most current defeat and then will he will make a decision regarding his future in the sport.

Haye's good friend and former world champion, Carl Froch, is practically pleading with Haye to retire before it's too late.

"There is only one answer about his future: David Haye should retire. 100 percent. Straight after the fight, I just went to see his mum and dad and told them to tell him to do the right thing and finish," Froch told Sky Sports.

"I don't like saying it but this has to be the end for him now. We have been friends for a long time and we have all been thrilled and entertained by his achievements, but I don't want to see this happen again. People shouldn't forget that as a boxer he has given us more than we ever expected. David did things beyond the call of duty.

"He was the undisputed cruiserweight champion of the world and then, to go on and win and be a heavyweight world champion, that says it all. But that has to be it now.  Remember he went 10 rounds on one leg, but although there was nothing like the same injury problems this time, David couldn't rekindle the flame."
