The bout will be held at UGMK Arena in Ekaterina, Russia. RCC Promotions will promote the event. In fighting Germany's Eifert, Bivol will fulfil his IBF mandatory obligation.

“On May 30, I'll be stepping into the ring,” The Ring, WBA, WBO and IBF champion Bivol said. “I promise to put on a beautiful and exciting fight. Two months of hard preparation ahead. I'll be glad to see each of you there!“

It’s been over a year since Bivol last fought. The 35-year-old avenged the lone defeat of his career by defeating Artur Beterbiev (21-1, 20 KOs) in their immediate rematch last February. In doing so, he became the light heavyweight division’s undisputed champion.

With their series tied at one apiece, there were talks of them getting it on for a third time. However, those discussions fell by the wayside as Bivol underwent back surgery.

Since then, Bivol (24-1, 12 KOs) has been hard at work getting himself back in shape. If he wanted, he could have chased a bigger name. But, with the IBF ordering him to fight Eifert in July, he decided to make his comeback against the sanctioning body’s No. 1 ranked contender, rather than get stripped.

For Eifert (13-1, 5 KOs), he’s been waiting for a shot at gold since beating former champion, Jean Pascal, in March 2023. He’s fought just once more since that victory, picking up a low-level win against Carlos Eduardo Jimenez in August 2024.

Bivol, who will be a massive favorite, has his eyes on bigger fights. The unified champion has mentioned fighting the likes of David Benavidez. Bivol was stripped of his WBC strap shortly after he was ordered to face Benavidez (31-0, 25 KOs) in early 2025. Bivol, however, vacated the title to pursue a third bout with Beterbiev. Benavidez, who held the interim version at the time, was immediately elevated. The 28-year-old is currently preparing to take on Gilberto “Zurdo” Ramirez for his WBA and WBO cruiserweight titles on May 2, but promised to come back down in weight to make a fight with the Russian star happen.

Bivol has also expressed interest in fighting Canelo Alvarez. They initially fought in 2022 with Bivol taking home a close but clear unanimous decision win.
