David Haye insists he is solely focused on trying to fully recover from shoulder surgery rather than making any decision about his boxing future.
The former WBA heavyweight champion has been advised by doctors to seriously consider hanging up his gloves after undergoing a five-hour operation in Germany last week to reconstruct his right shoulder.
However, Haye, who had been due to fight domestic rival Tyson Fury in February, is concentrating on getting a clean bill of health and not on whether or not he will retire from the sport.
"I'm just hoping I can recover. I'm not really thinking about boxing at all, it's just making sure I've got movement, and have the daily functions in my right arm that I had before. For me that's the most important thing at the moment," he told Sky Sports News.
The Londoner added when asked about thoughts of retirement:
"They've (the doctors) advised that, they believe throwing the shot that I throw, the Hayemaker, the big overhand right, is the worst shot I could possibly throw with the injury that I've got.
"They've had to reconstruct my shoulder, I had six pins in my shoulder connecting the tendons back to the bone.
"It's not ideal, but there's a lot of other stuff going on so I'm just trying not to drive myself mad about it. As long as my arm can still function normally, I'll be happy."
Although he has yet to confirm any decision about his future, Haye does concede that it will be virtually impossible to challenge at the top level of the sport without having his trademark 'Hayemaker' punch in his armoury.
"I could box probably, but just with my left hand and fighting at heavyweight with these big giant guys, I'm going to need the Hayemaker," he said.
"The Hayemaker's the difference, that's what keeps people at bay, it's what knocks people out.
"So once you take that away, it's like taking Joe Frazier's left hook or Muhammad Ali's jab, George Foreman's right hand - they cease being who they are, and my big overhand right is what I do best and once you take that away, I'll be a shell of the guy I was."
If he is forced to call time on boxing, Haye admits he would be proud of what he has achieved in his career, but would be disappointed he never got another chance to fight for a world title against either Vitali or Wladimir Klitschko, who defeated the Londoner two years ago..
"I've achieved my goal, I've achieved my lifelong ambition was to become the heavyweight champion of the world," he said.
"I've had my success, defended the heavyweight title a couple of times, so if this is it I haven't had a bad shout in boxing."
On whether he had any regrets, the 33-year-old added: "Ideally I'd want to beat all the best guys around.
"I wasn't able to beat Wladimir (Klitschko), he beat me on points. I always believed that I underperformed, that I could have done better, but it looks like I'll never get another opportunity to prove that now, which is a big shame but I'll have to live with that."
