If this was indeed his final fight, Joe Calzaghe left his fans on their feet begging for more.

The popular undefeated Welshman overcame a first-round knockdown to beat Roy Jones Jr. in a bloody unanimous decision Saturday night, delighting a raucous crowd at Madison Square Garden in what Calzaghe claims will be his final bout.

There is little left for him to prove after reigning as super middleweight champion for more than a decade, unifying the division, defeating Bernard Hopkins and now felling Jones _ possibly pounding him right into retirement as well.
