Pavlik is favoured to beat the fading Hopkins
Kelly Pavlik has refused to rise to Bernard Hopkins' bait ahead of their non-title super-middleweight clash.
Hopkins, 43, tried to goad Pavlik into betting $250,000 (£143,708) that he could win by a knockout on Saturday.
But the unbeaten WBO and WBC world middleweight champion said: "I haven't one fight, ever, predicted a KO.
"I don't train eight hard weeks just to knock somebody out. I go in there to win - 12 rounds. If a knockout comes, that's great."
Hopkins, who reigned at middleweight for 10 years, has never been knocked out. His most recent fight was a split-decision defeat by Joe Calzaghe in April.
Pavlik, 26, nicknamed 'The Ghost', has won 30 of his 34 career bouts by KO.
But the wily Hopkins (48-5-1), famous for outlasting his opponents, suggested his big-hitting fellow American will not be able to adjust his style in Atlantic City this weekend.
"The last I heard, Kelly Pavlik's been at his best knocking people out and coming forward and being himself," said 'The Executioner'.
"No matter what's been changed or what's been added on or what we're working on, that's great.
"But, trust me, when you're undefeated and never had to taste the taste of losing you're going to go back to what you're comfortable doing."
