Joe Calzaghe still expects to retire if he beats Roy Jones in November but has left the door open by admitting: "I'll never forgive myself if I lose my last fight".

The undefeated super- middleweight and light- heavyweight world champion has long maintained he intends to quit with his 100% record intact.

"At the moment I'm definitely going to retire," said the 36-year-old. "As long as I win and I win in style then it will be my last fight.

"I love boxing and I love what the sport has given me, but I want to retire undefeated."

Calzaghe will face Jones at New York's Madison Square Garden on November 8 after their original September date was postponed when the Welshman suffered a wrist injury.

Jones, 39, was regarded as the world's finest fighter until a shock defeat by Antonio Tarver in 2004 prompted a startling fall from grace.

"Roy Jones went through a bit of a tough time in his career but he's come back and had three great wins," said Calzaghe. "I can't underestimate him. I have to make sure I'm 100%.

"I normally prepare 12 weeks before a fight and I won't start sparring for another six weeks. So I'm ahead of schedule and have plenty of time to get in shape for the fight."
