Joe Calzaghe's September 20 showdown with Roy Jones Jr has been postponed, after it was confirmed the Welshman suffered a hand injury.
The huge light-heavyweight showdown in Madison Square Garden already had a cloud over it in the form of rumoured legal action by Calzaghe's former promoter Frank Warren.
What could well turn out to be Calzaghe's final fight will now have to be rescheduled anyway, however, as he has suffered a hand injury during training.
A November date has already been mooted although the New York venue may not be available.
The WBO and former WBC super-middleweight champion's camp are understood to have already started talks with American pay-per-view broadcaster HBO to try and arrange a new date for the fight.
Although the fight with Jones Jr is due to be Calzaghe's swansong before retirement, he could yet look at fighting super-middleweight star Kelly Pavlik as he has refused to relinquish WBO 12-stone title.
"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, told ESPN.
"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."
