Former undisputed heavyweight champion Lennox Lewis is urging Joe Calzaghe to retire. On Saturday night at New York's Madison Square Garden, Calzaghe (46-0, 32KOs) dominated Roy Jones Jr. over twelve rounds of action.

Lewis retired on top in 2003 and never returned to the ring. He says Calzaghe has nothing left to prove and should do the same.

"He's beaten everybody there is to beat and doesn't have anything else to prove, so I think he should retire," Lewis told BBC 5 Live's Sportsweek.

Former cruiserweight champ David Haye agreed with Lewis, asking Joe to hang them up.

"Very rarely do you get a fighter with his record retiring at the top. I think Lennox Lewis showed you can walk away from the game and stay away from it and get out on top. It depends on how much money he's got. If he's got enough money to comfortably have the lifestyle he wants then he would retire and if he hasn't then he'll only be fighting for the money, which a lot of boxers do later on in their career," Haye said. Fingers crossed he's tucked a bit away and he can have a nice lifestyle with his family."

Calzaghe former promoter, Frank Warren, wants Calzaghe to retire, but is not so sure of the Welshman hanging up the gloves.

"Before the fight he was saying it was his last fight and now he's saying he's not sure," said Warren, whose 12-year association with Calzaghe ended after the southpaw's victory over Bernard Hopkins in April," Warren said. "I believe he'll fight on. I would like to see him retire, he's got nothing else to prove and he's without doubt the greatest super-middleweight of all time.

"For me, he's the best British boxer since the war. His record speaks for itself. They say that fighters are the last people to know when it's time to give up but I think they're the last ones to admit it and that's what he needs to do."
