Brandon Adams and Caoimhin Agyarko will square off in an IBF junior middleweight title eliminator April 18 at Toyota Arena in Ontario, California.

Adams and Agyarko will headline a DMG Boxing show, sources told The Ring on Tuesday. A purse bid was scheduled for Tuesday afternoon, but a deal was struck just before it took place.

The winner between Adams (26-4, 16 KOs) and Agyarko (18-0, 7 KOs) will become the mandatory challenger to face champion Bakhram Murtazaliev. Russia’s Murtazaliev is set to defend his IBF belt against England’s Josh Kelly on January 31 in Newcastle, England.

Adams is ranked fifth by the IBF and Agyarko is seventh, but they are the two highest-rated available contenders after the third-ranked Kelly gets his shot. The top two spots in the IBF’s 154-pound rankings are vacant.

Adams, a 36-year-old from Los Angeles, is coming off a points win in a rematch against Serhii Bohachuk in September. Adams came into the clash as a heavy underdog despite knocking out Bohachuk in 2021 and dominated the 10-round sequel by unanimous decision.

Agyarko, a 29-year-old from Northern Ireland, will fight outside of the United Kingdom for the first time in his eight-year career. Agyarko was 3-0 last year, highlighted by a 12-round, split-decision win against Ishmael Davis in September and a 10-round, majority-decision win against Ryan Kelly in April.
