Ricky Hatton insists the idea of fighting Amir Khan "hasn't entered my head".
The 30-year-old has yet to make a decision on his future and admits he is not missing boxing since taking a break following his crushing second-round knockout by Manny Pacquiao in May.
Khan, meanwhile, won the WBA light-welterweight title with victory over Andreas Kotelnik on Saturday to further fuel talk of a showdown between the two Lancashire fighters.
However, Hatton - who has been released from hospital after a bad stomach bug - told the Manchester Evening News: "I'm not thinking about boxing at the moment. Maybe I'll wake up one day and think let's give it another go, but I might not.
"I'm not missing it. Fighting is the furthest thing from my mind.
"I'm delighted for Amir. I can't praise him enough. He's gone back to the drawing board and answered any questions there might have been about him.
"But the fact that he's won a world title has not made me any closer to a comeback. It hasn't entered my head.
"I don't think I have to beat Amir Khan to prove anything."
Hatton, who has lost two of his last four fights having been defeated by Floyd Mayweather Jr in December 2007, added: "When I look back at my career nobody expected me to do what I've done.
"I won five titles at two different weights. I've only lost to the pound-for-pound best fighters in the world. If I don't fight again I can hold my head high.
"Maybe somewhere down the line I might think about giving it another go and if he is still world champion then obviously he would be a possibility."
