Oleksandr Usyk will make his heavyweight debut in Chicago this weekend despite Tyrone Spong’s failed drugs test.
Usyk was last in action in November when he beat Briton’s Tony Bellew by KO at the Manchester Arena.
The Ukrainian retained his cruiserweight titles with that victory but now he is set for a new challenge.
He will make the leap up to the heavyweight division this Saturday and was set to face undefeated Spong.
But that fight was called off after the Surinamese-Dutchman returned adverse drugs tests and now Usyk will take on 38-year-old American Chazz Witherspoon.
Usyk vs Witherspoon: Date and start time
The fight is set for Saturday, October 12 and is being held at Wintrust Arena in Chicago, Illinois.
The main event ring walks should start at around 4am on Sunday UK time.

Usyk vs Witherspoon: What has been said?
Oleksandr Usyk: “There have been no problems in order to move to the heavyweight division.
“At least to me there have been no problems. I simply moved to the heavyweight division, and that was it. Virtually nothing has changed in my training, we’ve simply started doing even more work. Different, and hard work, which is practising with big guys who pose a great threat.
“I’m really looking forward to boxing on October 12. I very much missed the boxing. I love boxing, and really there is a lot of talk about it, but I’m not paying attention to it. My objective is to do my job in the gym in order to show all the enthusiasts and fans great boxing in the ring.”
Chazz Witherspoon: “Oleksandr is stepping up to heavyweight – and he’s going to find out that it’s a totally different game.
“I’ve won my last eight fights and I really feel that I’ve been waiting in the wings for a huge opportunity like this and I am going to put every ounce of myself into the fight on this massive stage.”
