UPDATE: A purse bid for an IBF heavyweight eliminator is back on the books after a few previous postponements.. The promotional rights to a potential Frank Sanchez vs. Efe Ajagba rematch is scheduled to be  auctioned off on Tuesday, August 26, 2025 at 12 noon. Sanchez defeated Ajagba by unanimous decision in 2021, but with heavyweight contenders Filip Hrgovic and Derek Chisora jockeying for bigger fights, Sanchez and Ajagba are the two highest ranked fighters in the IBF ratings to enter the elimination process. Undefeated world champion Oleksandr Usyk owns all four major heavyweight titles, including the IBF version.
