More than a month after losing the biggest fight of his career to Gennady Golovkin, Geale has confirmed his next opponent will be another Australian on the rebound from a failed middleweight world title shot in New York.

Fletcher is a 30-year-old Queenslander who went through the Australian Institute of Sport with Geale before the pair shared numerous overseas trips, including the 2002 Commonwealth Games in Manchester where the Tasmanian won a gold medal.

Geale told The Examiner yesterday that he would fight Fletcher in early December, probably either in Sydney or Brisbane.

"He threw out a challenge to me and we accepted it," said the 33-year-old Launceston fighter.

"I've known him a long time and when you first think about fighting a mate it is a bit awkward, but business is business and you've just got to get on with it.

"We'll shake hands afterwards and probably share a beer, but in the ring we're enemies."

Just a couple of weeks after Geale lost the IBO and WBA super middleweight world title fight against Golovkin at Madison Square Garden, Fletcher was in the same city losing a WBA title to Brooklyn's Daniel Jacobs.

Geale said the Victorian-born, Hervey Bay-based Fletcher, who won a Commonwealth title of his own in 2006, was an ideal opponent as he seeks to retrieve enough ranking points for another shot at Golovkin.

"It's going to be a tough fight because he's a good smart boxer with a good jab," he said.

"But I don't think he has slipped into the professional mould yet and that's something I'll want to take advantage of.

"This sort of fight should keep me high up in the rankings, which is what we want to line up another world title fight."

Fletcher has won 18 of his 20 pro fights.
