Deontay Wilder will defend his WBC heavyweight title against Dominic Breazeale on May 18 at the Barclays Center.
The two fighters were present as the bout, which will be broadcast live in the United States by Showtime, was announced to the media at the venue in Brooklyn on Tuesday.
Wilder is unbeaten in 41 fights, though his 100 percent win record ended last time out when he drew with Tyson Fury.
A rematch between the pair was initially on the cards, but a failure to agree to a second meeting led to the WBC ordering their champion face his mandatory challenger next instead.
Breazeale was stopped by Anthony Joshua when challenging for the IBF title back in June 2016 but is confident he will put an end to Wilder's plan to unify the division.
Breazeale is now working with trainer Virgil Hunter, who is best known for his partnership with former two-weight world champion Andre Ward.
“I want to prove to the world that I’m the best. That’s what I believe in my heart. Until someone proves me wrong, I will continue to believe that. Breazeale is the next man in line. I can’t wait for this one," Wilder said.
“I’m just going to show everyone on May 18. The way I feel right now, the fight could be this week. The champion must always be ready for whatever a challenger can bring.
“I hope he’s training his hardest. I’m glad he has Virgil Hunter on his side to show him something new. Every man I’ve faced; they’ve landed on the canvas. I’m going to continue to do that on May 18.
“No man who gets in the ring will be able to defeat Deontay Wilder. I hold the keys to the heavyweight division. No fighter is doing what I’m doing. I’m trying to give the fans something they’ve never seen before.
“Enjoy this one, because it’s going to be a massacre. May 18 will be a beautiful day for me and a beautiful day to see what I’m planning to do for the sport of boxing.”
