Boxing: Lennox Lewis believes he is the last of the great heavyweight boxers and plans on taking his final bow in the ring in true champion's style

Lewis defends his World Boxing Council title against Ukraine's Vitali Klitschko in Los Angeles on Saturday night but is already looking at a swansong showdown with Roy Jones Jnr later this year.

"I am the last great heavyweight," said Lewis. "I don't see any others accomplishing what I have throughout my entire career."

Lewis reckons the heavyweight scene will still be the pinnacle of boxing when he does bring his 14-year career to an end even though there appears no line of succession.

"When you get such huge men competing, just the size, power and the grit of it, it is always exciting. It's the king of all weight classes," added the 37-year-old.

Lewis, who swept into the training hall in the LA Boxing Club surrounded by a huge army of family, friends, trainers and bodyguards, did not look like a man with retirement on his mind as he focused on seeing off the threat posed by the younger - and taller - Klitschko.

But the former Olympic champion admitted it would be a natural time to quit after fighting Jones in November - if the American was crazy enough to get into the ring with him. Jones is widely regarded as the best pound-for-pound fighter around having made the move up from middleweight to claim the World Boxing Association's heavyweight title with victory over John Ruiz.

Yet despite his speed, Jones would have such a massive height and weight disadvantage compared to Lewis that it might need a huge pay day to entice him into a bout.
