The Raiders and two-time Pro Bowl offensive lineman Jeremy Newberry agreed to a $1.5 million, one-year contract Wednesday, hoping to boost a struggling offensive line. Newberry, a Pro Bowler in 2001-02 with San Francisco, spent all of last season on injured reserve with the 49ers with an damaged left knee. He has played in only 11 games the past three seasons because of various injuries. But the Raiders are counting him to help an offensive line that allowed a league-worst 72 sacks last season.
