Mike Tyson is to fight again in a veterans tournament, say reports.
Tyson announced his retirement from the ring after a humiliating loss to Irish journeyman Kevin McBride on 11 June.
But his promoter Jeff Fenech has begun negotiations for a series of four-round bouts, possibly involving Tyson's arch-rival Evander Holyfield.
"Mike believes he can still thrill fans with the style that made him the youngest heavyweight champ," Fenech told Australia's Daily Telegraph.
"Mike does not want to go out of boxing as a loser against Kevin McBride.
"He is one of the greatest heavyweight champions of all time and is still explosive for four rounds.
"He doesn't want to compete in 10-round fights because after 20 years as a big-name fighter it is hard to keep backing up in the gym.
"But physically he remains rock solid and very strong."
Following his loss to McBride, Tyson vowed never to set foot in a boxing ring again.
"I'm not going to fight again. I haven't got the fighting guts or the heart any more," said the 38-year-old.
"I was just fighting to pay off the bills. I'm not an animal anymore and I'm not going to embarrass this sport."
Riddick Bowe, another former world heavyweight champion who recently returned after an eight-year lay-off, has also been mentioned.
Bowe, 37, has never fought Tyson but edged a classic trilogy with Holyfield between 1992 and 1995.
Holyfield beat Tyson twice in 1996 and 1997, although Tyson was disqualified in the rematch for biting off a part of Holyfield's ear.
Holyfield, 42, has won just two of his last nine bouts and was last seen appearing on the American version of Strictly Come Dancing.
