On Saturday night, undefeated super middleweight champ Joe Calzaghe will be fighting in the United States for the first time when he moves up to light heavyweight (for the first time in over a decade) to take on future Hall of Famer Bernard Hopkins. The 12-round fight will be broadcast live on HBO (not PPV!) at 9:45pm ET.

Oddsmakers favor Calzaghe, 36, over the 43-year-old Hopkins at between 5-2 and 3-1 -- a surprisingly wide margin given how good Hopkins looked in defeating Winky Wright and Antonio Tarver in his two most recent outings. While this is clearly the biggest fight of Calzaghe's career, he was at his best in the two biggest fights of his career to date: lopsided decision victories over previously undefeated Jeff Lacy in 2006 and Mikkel Kessler in 2007.

Prediction: No one ever looks great against Hopkins and he will undoubtedly attempt to rough up Calzaghe, who has already voiced concern over possible head butts and low blows. Calzaghe will have to be strong mentally as he will not only have to deal with Hopkins, but also with a crowd that will not be entirely in his corner. The bet here is that Calzaghe is up for the challenge. Hopkins will make the fight ugly and hard to score, but Calzaghe will simply be busier and win rounds by outworking his older foe. This one is going the full 12 rounds with no knockdowns. Calzaghe by close unanimous decision ... though Hopkins will say he was robbed.
