The Raiders released offensive lineman Adam Treu on Tuesday, cutting ties with the longest-tenured player with the team. Treu had been with the team since being selected in the third round of the 1997 draft. His streak of 155 consecutive games played was snapped last season when he was sidelined with a torn quad muscle in his right leg. He played on the offensive line, as well as serving as the team's long snapper. The Raiders also released fullback Tony Jackson, who was on the practice squad last season.
