Oliver Zaren (19-0-1, 8 KOs) lacks major name recognition, though he owns the IBF Intercontinental title and is ranked No. Christian Mbilli defends his WBC belt against Canelo Alvarez on October 31, three weeks after Iglesias faces Zaren. Osleys has struggled to secure a major opponent despite his knockout run. With the division’s better-known champions and contenders committed elsewhere, Zaren gives him a title defense without forcing him to wait several more months for another opportunity. The bigger fights remain the goal at 168 pounds, and Zaren isn’t the type of opponent who will satisfy that demand.
