“This time I’m serious. I’m going to do some damage here, on Saturday night.”
“I’m going to dish out a whole lot of pain. I’m going to put (Usyk) in the hurt locker, for sure,” added Fury.
Usyk refused to indulge in trash-talk and shrugged off the hoopla of the packed press conference at VIA Riyadh, a swanky mall in the Saudi capital.
“Now we have just a performance, those cameras, lights,” he said, in comments translated by his promoter Alex Krassyuk.
“Everything’s going to take place on Saturday night.”
Usyk, 37, takes a 22-0 record into Saturday’s fight at Kingdom Arena, including six victories since the former undisputed cruiserweight champion stepped up a division.
“Gypsy King” Fury, 36, is 34-1-1 and bidding to avenge his sole career loss suffered seven months ago at the hands of the skilful Usyk.
British media have reported a prize purse of £150 million ($190 million), with Usyk expected to receive the bigger share.
Oil-rich Saudi Arabia is investing heavily in sport to raise its profile, prompting accusations of “sportswashing”, or using sport to distract from its human rights record.
