WBC heavyweight champion Deontay Wilder wants to hurt Dominic Breazeale "so bad" as the American star unleashed a chilling tirade at his opponent.

Wilder has already said Breazeale's body is on the line in Brooklyn this weekend – the titleholder reiterating his desire to kill in the ring – and he continued his tough talk ahead of Saturday's showdown.

Set to make his ninth title defence at Barclays Center, Wilder's comments did not go unnoticed by WBC president Mauricio Sulaiman on Thursday.

However, Wilder (40-0-1) was in no mood to back down as the fighters came face-to-face during their final news conference.

"This has been a long time coming for me and Dominic. He asked for this, and he shall receive. Just like the Bible says - you ask, you shall receive," Wilder told reporters.

"Come May 18 at the Barclays Center, he's going to get everything he receives. I'm gonna fade him out, baby. I can't wait. It's gonna be an amazing night for me and sad time for him.

"I want to hurt Breazeale so bad. So bad, my blood is boiling right now. I can barely keep my composure right now. But due to the fact we can't get paid outside of the ring - there's a lot of money on the line, baby, and my family got to eat.

"So with that being said I will keep my composure until that time comes. I can't wait. Come Saturday, I can do whatever I want to do. You better gather around your loved ones. You all better gather around him tonight because come Saturday night, he may not be able to talk to you. Trust me. You know I don't play no games.

And Wilder added: "If anybody thinks this is a game, you better close your eyes when the TV comes on. Or, if you’re there, you better bring your blindfold.

“Because this is gonna be a tragedy. It’s gonna be a tragedy. The least I can do [for his family], I can pay for the funeral.”

Breazeale (20-1), meanwhile, said: "I'm excited to be back and get another knockout win. Getting that WBC belt is everything to me. This is my Super Bowl. Victory for me on Saturday is everything. Wilder doesn't know what he's getting himself into.

"He's in for a fight. He better be confident in his abilities because Saturday night, he's going to be in the toughest fight of his life. I'm going to beat Deontay so bad that he's not going to ever want to lace up the gloves again."
