Former champion Guillermo Rigondeaux was scheduled to take on Liborio Solis in the co-feature of the Harrison-Charlo rematch this Saturday on FOX, but that match has been postponed until a later date. In the new co-feature at the Toyota Arena in Ontario, California, heavyweight Efe Ajagba (11-0, 9 KOs) takes on Iago Kiladze (26-4-1, 18 KOs) in a 10-rounder. Also, the new opening bout on the telecast is 2016 U.S. Olympian Karlos Balderas (9-0, 8 KOs) against Rene Tellez Giron (13-1, 7 KOs) in an eight-round lightweight match.
The originally scheduled FOX opener between middleweights Hugo Centeno, Jr. and Juan Macias Montiel will now headline an FS1 card preceding the FOX telecast. In the co-feature on FS1, undefeated featherweight contender Jhack Tepora (23-0, 17 KOs) will battle former title challenger Oscar Escandon (25-5, 17 KOs) in a 10-round bout. Super welterweight prospect Raymond Guajardo faces Donnis Reed in a four-rounder in the televised opener.
