Boxing: Calzaghe decides to throw in the towel after 'two fights, tops'

Joe Calzaghe, the newly crowned BBC Sports Personality of the Year, says his next fight could be his last. Calzaghe, who turns 35 in March, unified the three world titles in the super-middleweight division when he beat Mikkel Kessler of Denmark last month, taking his record to 44-0.

"I have got two fights left tops," he said yesterday. "I might even have one more and then decide to pack it all in and then get on with the rest of my life. Who knows? There are plenty of other things I want to do. I don't want to fight on for money. That's not the right motivation."

After beating Kessler, Calzaghe said he would like to step up a division and challenge Bernard Hopkins at light-heavyweight. Although no deal has yet been finalised, Calzaghe has all the motivation he needs, after Hopkins said, "I would never let a white boy beat me. You can print that."

Calzaghe added: "I need to have a goal, like Hopkins. It has to be something big to motivate me. Very few fighters go out as unbeaten champs. Rocky Marciano did and that's how I want to go out."
