According to Richard Cloutier, the newly opened televised slot on the Pacquiao-Margarito undercard will be filled by a bout between Brandon Rios and Omri Lowther. The spot became vacant when Kelly Pavlik pulled out with an injury. Yes, this is short notice, but this is a much worse opponent than even I would have expected and adds zero to the undercard. His last time out, Lowther was dominated by Hank Lundy in a fight that Lundy took on four days' notice. Expect to hear Rios's signature grito sometime before the scheduled fourth round.
