Beterbiev (20-0, 20), the WBC, WBO and IBF titleholder, is the only boxing champion with a 100% knockout rate. He has been the 175-pound champion since 2017.

The fight lasted years. Since Roy Jones Jr. lost one of his titles in 2000 (three belt era), there has not been an undisputed champion in the division.

“I want a good fight. I’m preparing for a good fight,” Beterbiev said during a press conference on Thursday. “We’ll see. …Be ready, Dmitry. I’ll be ready.”

Bivol (23-0, 12 KOs), the WBA champion, was promoted from interim titlist to full titleholder in 2017 and has defended the belt 12 times since then.

The fight between Beterbiev and Bivol was scheduled to take place on June 1, but a month before the fight, Beterbiev suffered a torn meniscus and had to undergo knee surgery, forcing the postponement. Wanting to stay busy, Bivol fought Malik Zinad that day, a sixth-round TKO win, his only stoppage win in his last 10 fights.

“Artur is a great champion,” said Bivol. “He has what I want. He has the belts. And it’s not just about belts. When I look at his skills, I also want to test my skills against this great fighter.”
