The 35-year-old IBF, WBA, and WBO light heavyweight champion Dmitry Bivol (24-1, 12 KOs) returns May 30 against IBF mandatory Michael Eifert (13-1, 5 KOs) at the UMMC Arena in Ekaterinburg, Russia. The fight marks Bivol’s first appearance since undergoing back surgery in August 2025 to repair a long-standing herniated disc.
On the Inside The Ring show, Max Kellerman pointed to a common concern for fighters returning from similar procedures.
“Usually, guys aren’t the same after back surgery,” Kellerman said.
That concern becomes more specific with Bivol, whose style relies heavily on footwork, spacing, and constant in-and-out movement. Michael Coppinger highlighted that dependency while assessing the matchup.
“That’s true, especially a guy in Bivol, who really uses that movement. He comes in like fencing in and out. He needs to be at his,” Coppinger said, before noting that Eifert represents a credible test despite limited top-level experience.
The February 2025 rematch with Beterbiev was a career-defining win for Bivol, but it clearly took a toll. Even though Bivol won the majority decision to become undisputed, that 12th round was a car crash. Taking that kind of fire at 34, then immediately heading into a major surgery for a 10-year-old injury, often triggers a “physical cliff.”
When a fighter relies on rhythm and twitch reflexes, like Bivol’s “fencing” style, the margin for error is razor-thin. If he’s lost even 5% of his lateral speed, he becomes hit-able.
Eifert’s best win came against former champion Jean Pascal in 2023, though Pascal was 40 at the time. Still, the mandatory position places Bivol in a situation where he must perform immediately following a layoff tied to surgery.
“There’s no good options if you’ve got a bad back,” Kellerman added. “You better look good against Eifert. Get rid of that rust to see how he can move around.”
Dmitry is expected to pursue a third fight with Artur Beterbiev or a bout with David Benavidez later this year, making his condition against Eifert a key early indicator.
Bivol has won 24 of 25 fights by controlling distance and pace, and that style leaves little margin if his movement is affected.
