Dmitrii Bivol vs Callum Smith IBF WBO World Light Heavyweight

Dmitry Bivol (25-1, 12 KOs) defends his light heavyweight titles against mandatory challenger Callum Smith (31-2, 22 KOs) in Yekaterinburg.
The 35-year-old Bivol returns after elbow surgery in July. He reclaimed the undisputed crown by beating Artur Beterbiev in their February 2025 rematch, then gave up the WBC belt while chasing a trilogy that never happened. He came back from more than a year out in May with a wide decision over Michael Eifert.
