The Raiders signed veteran free-agent quarterback Marques Tuiasosopo yesterday. Terms of the deal were not disclosed. The move brings the career backup QB back to the team that drafted him and it’s expected he’ll battle Andrew Walter for the position behind starter JaMarcus Russell. The Raiders originally selected Tuiasosopo in the second round of the 2001 Draft. The 29-year old former University of Washington star spent last season with the New York Jets but never saw any playing time. During his stay with the “Silver and Black,” Tuiasosopo completed 48 of 88 passes for 550 yards and two touchdowns in 11 games. He finished his college career with 5,501 passing yards and 31 touchdowns while also rushing for 1,374 yards, a school-record for QBs, and 20 scores.
