Ovill McKenzie has vowed to finish Tony Bellew inside nine minutes when they meet next weekend.
The pair clash in a British and Commonwealth light-heavyweight title fight at the Liverpool Echo Arena.
It's a rematch of their first meeting in December.
In that fight, McKenzie twice had Bellew on the floor before the champion rallied for his win.
"I'm going to knock him out inside three rounds," said McKenzie today during a heated conference call.
The Derby man has upset Bellew after accusing him of being on drugs in their first fight.
But today McKenzie said: "My accusation is fair.
"In December last year I said I don't know if this guy is on drugs, but he looks like he's on drugs.
"On July 16 we have two drugs test, one before the fight, one after the fight and I don't see a problem with that."
But Bellew hit back by saying: "I'm looking forward to ramming the accusations down his throat. He's clutching at all the straws he possibly can.
"Why are you trying to drag our sport through the mud?" he told McKenzie.
"You've made our sport look stupid but you're the one who is going to look stupid because I'm going to smash you from pillar to post."
