Boxing: Lewis set to retire after re-match with Klitschko

Lennox Lewis says his proposed re-match against Vitali Klitschko is likely to be his last defence of his world title. Negotiations for the rematch are already under way and the fight could take place on 6 December.

The world heavyweight champion beat Klitschko on a sixth-round technical knock-out in Los Angeles last month. Lewis said that he will wait until the negotiations with Klitschko are concluded before finally deciding his future.

Asked if he would retire after a re-match, Lewis said: "Yeah I think so. I'm going to make a wise decision in the near future. I would have nothing left to prove. Even now I have nothing left to prove. I'm just basically boxing for the fun of it."

"Other people are hyped up about the Klitschko fight and obviously they want to see another one," Lewis said. "I enjoyed the first one. Right now we are just working out the logistics and talking to his manager and HBO [the American pay-per-view cable television company] to see what we can work out."

Despite the uncertainty surrounding his future, Lewis dismissed suggestions that he may have lost his motivation.

"If a man thinks he can beat me I'm out to prove him wrong," said the Briton. "I've already proven that I can beat Klitschko on my worst day."
