The Raiders on Tuesday announced that they have released offensive lineman Adam Treu.  The longtime center was with theTreu Raiders for 11 seasons, the  longest-tenured player with the team. He was a third-round pick out of Nebraska, and at one point in his career played in 155 straight games.  That streak ended last year with a torn quad in his right leg.  He was a starter for the Raiders in 44 of the 155 games played. He played on the offensive line, as well as serving as the team’s long snapper.
