Lewis pledges to concentrate on Klitschko KO

Lennox Lewis insists there will be no complacency when he defends his world heavyweight crown in Los Angeles tomorrow by entering the ring the heaviest he has ever been for a title fight.

The 37-year-old tipped the scales at a massive 18st 4lb at the Staples Centre yesterday – eight pounds heavier than challenger Vitali Klitschko even though Lewis is almost three inches shorter than the Ukrainian.
