David Haye insists he remains in the dark about whether or not he will return to the ring.
The 33-year-old former world heavyweight champion put his future on hold after he underwent a five-hour operation in Germany to repair severely ruptured tendons in his right arm in November.
The surgery forced him to withdraw from his keenly-anticipated grudge match with fellow Brit Tyson Fury and he admitted at the time that his career could be over.
However, the Bermondsey-born fighter is refusing to give up on a return, although he admits there is no timescale on a potential comeback.
He said: "You talk to 10 doctors, 50 per cent say you can make a recovery and 50 per cent say, 'no you're done, you'll never be able to throw a punch again otherwise your arm will fall out of its socket'.
"It's just down to how the rehab takes, I'm doing that every day, I'm doing the best I can. No one knows how long it's going to take, no one knows how it's going to heal.
"At the moment I can't throw a punch, so hopefully in a few months I'll be able to throw one, but you never know.
"I can't say 100 per cent yes or 100 per cent no, I'm just taking every day at a time. I won't know anything for a good few months yet. My shoulder's bad enough that I can't even run yet.
"That shows you how far away I am from being able to punch. It's going to take a little while, but I'm working hard on the rehab.
"I've just got to be patient and keep a low profile, and when I do have news, good or bad, I'll let everyone know. Best-case scenario my arm gets back and it's just as good as it was before it busted.
"And then I think I've got a lot left I believe, I think I've got a few more good fights left in me, if this arm can get back on track."
David Haye was speaking at the Blu-ray launch of the Rocky Heavyweight Collection, which is out now.
