Carl Froch's Super Six World Boxing Final bout with American Andre Ward has been rescheduled for 17 December in Atlantic City.
The duo were set to fight to unify their super-middleweight titles at the same venue on 29 October.
But that fight had to be postponed after WBA champion Ward sustained a cut above his right eye during a training session last week.
WBC champion Froch reclaimed his title by beating Arthur Abraham in November.
Froch was first crowned WBC super-middleweight champion in December 2008.
The 34-year-old beat Canadian Jean Pascal, before going on to retain the title twice more before losing on points to Mikkel Kessler in April 2010 - his only professional defeat to date.
He regained the title seven months later when he was named the undisputed winner against Abraham in Helsinki.
