BoxingScene.com was advised by sources close to the situation that Bernabe Concepcion (28-4, 15KOs) and Ricardo Cordoba (37-2-2, 23KOs) are two of the names being mentioned as candidates to face two-time Olympic gold medal winner Guillermo Rigondeaux (6-0, 5KOs) on the Manny Pacquiao-Antonio Margarito undercard on November 13 in Arlington, Texas. Cordoba is said to be the prefered option for Rigondeaux.

BoxingScene.com confirmed earlier that former middleweight champion Kelly Pavlik is in talks with Top Rank to return on the Pacquiao-Margarito undercard, and welterweight Mike Jones is another strong possibility for the show.
