Former IBF junior middleweight champion Raul Marquez steps back in the ring next Friday at the Convention Center in Pasadena, Texas against yet another former Vernon Forrest opponent in Elco Garcia.Marquez, 37-3, scored a fifth round stoppage over previous Forrest victim Sergio Rios in July. A win against the 18-5 Garcia could put Marquez in a position for a possible fight with Forrest. Also, WBA lightweight champion Juan Diaz, who as first reported by Boxingtalk, is on the verge of signing with Golden Boy Productions, will possibly be fighting an exhibition on September 23, 2006 on a card to be headlined by his younger brother Jose Diaz, 12-0, against an still-to-be named opponent.
