IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua will be looking to do some brutal damage on June 1.
Joshua will defend his four belts against once-beaten Andy Ruiz, at Madison Square Garden in New York City.
The contest will be Joshua's United States debut as a professional.
Andy Ruiz will enter the fight on late notice, after replacing original opponent Jarrell Miller.
Miller was removed from the fight after coming up positive for performance enhancing drugs in three separate tests.
But Ruiz has not been inactive. He only fought last month, when he battered and stopped Alexander Dimitrenko in five rounds in California.
"I'm looking forward to the training camp. The goal is always to look above, beyond, and past anyone. I want to be the best, leading the pack,and not caring about who is beside me, because I want to be far ahead. I'm training hard, and I want to demolish Anthony Ruiz in good fashion and then I look forward to more competitive fights," Joshua told Sky Sports.
Ruiz has never been hurt, and he's never been down.
Joshua has been staggered in more than one contest and Wladimir Klitschko dropped him hard in their high profile contest back in 2017.
He expects Ruiz to come guns blazing, looking to land big shots on the chin.
"Ruiz has never been hurt, he's a strong guy. I've been hurt and people have seen me put down. Dillian Whyte caught me with a sweet left hook, so they have seen my weaknesses, and I haven't really seen a weakness in Andy Ruiz," Joshua said.
"He's going to try and exploit my weaknesses, and I'm going to try and exploit his. The best man will win and raise their hand at the end of the night and we will shake hands and go about our business."
