Joe Calzaghe is hoping to rearrange his bout with Roy Jones Jr after spraining a wrist in training.

Calzaghe and Jones were due to fight on September 20 at Madison Square Garden, but the bout could be put back until November.

Calzaghe's father and trainer, Enzo, said: "He sprained his wrists on the pads. It's one of those things you never want to happen, but it's happened.

"When he woke up in the morning with a swollen wrist, I looked at it and it looked awful.

"It is a sad thing it happened and he needs two or three weeks off before he starts punching again.

"Everybody's gutted about it. Joe's absolutely distraught. What can you do about it? You've got to have common sense in this game. At the end of the day at this level you need to be safe."

Calzaghe's right wrist has been examined by a specialist and a source close to the light-heavyweight said the problem is "not career-threatening".

John Wirt, chief executive of Jones Jnr's promotional company Square Ring, said: "We're trying to reschedule for November, and that works for them, so the injury must be something they feel will heal sufficiently by then.

"Roy is disappointed but he's looking forward to the fight being rescheduled.

"But this may be a blessing in disguise because it gives us more time to promote the fight. We were under the gun putting everything together quickly."
