8/28/2026, 12:09:07 AM
Core Agreement
The World Boxing Organization (WBO) announced that champion Dmitrii Bivol and mandatory challenger Callum Smith have reached a written agreement on fight terms, including a date and venue, after the sanctioning body’s deadline of August 27 to avoid a purse-bid. The specific location and calendar details have not yet been released by the promoters.
Background & Context
Bivol, the 35-year-old Russian who holds the WBO, IBF, WBA and The Ring light-heavyweight belts, returned from a 15-month layoff caused by back surgery with a unanimous-decision victory over Michael Eifert on May 30 in Russia. Earlier in his career he traded wins with Artur Beterbiev, losing a majority decision in Saudi Arabia before regaining the undisputed status in their rematch four months later.
Smith, 36, captured the WBO interim light-heavyweight title by defeating Joshua Buatsi on February 22 in Riyadh. He was scheduled to fight David Morrell on April 18, but withdrew after an injury in training camp. Morrell subsequently faced Zak Chelli on May 9, winning by stoppage in the tenth round, prompting the WBO to order Bivol versus Smith.
Data & Statistics
- Dmitrii Bivol: 25-1 record, 12 knockouts.
- Callum Smith: 30-2 record, 22 knockouts.
- Bivol’s May 30 win was a lopsided unanimous decision (Ringmagazine, Ringside24).
- Smith’s last bout before the agreement was a February 22 victory over Buatsi.
Official Statements & Responses
WBO president Gustavo Olivieri confirmed on August 27 2026 that the organization received written confirmation from RCC Boxing on behalf of Bivol and Matchroom Boxing on behalf of Smith, indicating that both camps have agreed to the fight terms and identified a date and venue. The WBO noted that it will defer to the promoters for the public announcement of those details.
Why It Matters
The matchup fulfills a mandatory defense for Bivol, potentially limiting his ability to pursue larger-ticket unification fights that were being explored after his spring comeback. For Smith, the bout offers a chance to become a two-division champion and to re-establish himself at the top of the 175-pound division. The outcome will shape the light-heavyweight landscape, either cementing Bivol’s grip on multiple belts or opening the division to a new set of marquee contests.
