British boxer

Joe Calzaghe

says his next fight could be his last.

Calzaghe 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," Calzaghe was quoted as saying in yesterday's editions of the Daily Mirror. "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.

"My next fight could most definitely be my last. 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 light heavyweight Bernard Hopkins, but no deal has been finalized.

"I need to have a goal, like Hopkins," said Calzaghe, who turns 36 in March. "It has to be something big to motivate me."
