Former champ Lewis says Calzaghe should follow his lead and retire on top

LONDON -- Lennox Lewis thinks Joe Calzaghe should quit after defeating Roy Jones Jr.

Calzaghe survived a first-round knockdown to improve to 46-0, battering a bloody Jones in a unanimous decision Saturday night at Madison Square Garden.

"Joe has beaten everyone there is to beat and has nothing else to prove, so I think he should retire," said Lewis, who retired in 2004 when he was still world heavyweight champion.

Calzaghe announced before the light heavyweight fight that it would his last, but said afterward he might not stick to his retirement plans.

Frank Warren, the Welshman's former promoter, believes he will fight on despite having nothing to prove after victories over Jones and Bernard Hopkins.

David Haye, the former world cruiserweight champion who fights for the first time as a heavyweight when he meets Monte Barrett next Saturday, said Calzaghe should quit to preserve his unbeaten record instead of chasing bigger paydays.

"Very rarely do you get a guy with his kind of record retire on top form," Haye said. "Lennox Lewis showed you can walk away from the game and stay away from it. Roy Jones should have retired after he beat John Ruiz, but he tainted his legacy by carrying on."
