The pair were due to face off in a light-heavyweight fight at New York’s Madison Square Garden on September 20 but the Briton injured his right hand in training.
A source close to Calzaghe has insisted the problem is “not career-threatening” and he saw a consultant yesterday in an attempt to ascertain its exact nature. Talks began almost immediately with Jones Jr’s representatives, American pay-per-view channel HBO and officials from the venue in order to set a new date for the contest.
“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,” John Wirt, chief executive of Jones Jr’s promotional company Square Ring said.
“Roy is disappointed 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.”
Calzaghe has suffered a string of hand injuries in the past – although the majority were to his left.
The fight with Jones Jr was widely expected to be Calzaghe’s last before retirement, but he has refused to relinquish his WBO super-middleweight title ahead of the contest and last week suggested he could take on Kelly Pavlik at 12 stone next year.
The 36-year-old Welshman is the longest reigning champion in his sport, having defended the WBO belt 21 times, four short of the all-time record for consecutive defences held by heavyweight great Joe Louis.
