Calzaghe vows to go out with a bang
The 36-year-old has not been defeated in 45 fights, having dominated the super middleweight division for a decade between 1997 and 2007.
Calzaghe then moved up to light heavyweight and edged a split decision over Bernard Hopkins in Las Vegas in April and is now in New York preparing for his swansong against 39-year-old Jones, an eight-time champion in four different weight classes from middleweight to heavyweight.
