Ricky Burns has said he will only find out if he can continue with his career when he returns to sparring.
The WBO lightweight champion had his jaw broken in his last fight against Ray Beltran, one that was controversially scored a draw by the judges.
Both Burns and promoter Eddie Hearn are hoping the Scot will be fit to make a mandatory defence against Terence Crawford in the New Year, although Burns is not getting ahead of himself.
"The jaw is getting there, healing the way it should do, I'm in light training but no boxing for another four to five weeks," he told Sky Sports.
"When I say light training I mean swimming or cycling, even jogging I need to stay away from. There's nerve damage, it's still numb but it's getting there.
"The surgeons said my jaw should go back to where it was and hopefully when I start back sparring all those doubts will be put to rest.
"I will need to take a couple of clean shots to put my mind at ease. But I just need time for it to heal and have another x-ray to make sure it's all healed."
Burns is aware that he was fortunate to retain his title in Glasgow and is quite happy to take on Beltran once more.
"I was talking to Eddie, we are hoping it's going to be January/February time but we'll know a bit more over the next few weeks," he added.
"I'm up for fighting anybody and Terence Crawford is my mandatory challenger. Beltran does deserve a rematch, everyone who knows me knows that wasn't me from the second round on - I was in survival mode.
"There's definitely unfinished business I need to take care of."
