Matt Shaughnessy out for year

There have been indications over the past couple of weeks that Oakland defensive end Matt Shaughnessy could be out for the season with a shoulder injury. The Raiders made the news official Wednesday when they put Shaughnessy on the injured reserve to make room for newly-acquired quarterback Carson Palmer.

Shaugnhessy has been out for the past three games and Oakland coach Hue Jackson recently indicated that he could be out for the long haul. The third-year end makes a lot of plays and still has a strong future. The Raiders are deep on the defensive line, though. Desmond Bryant, Trevor Scott and Jarvis Moss will all continue to work in the rotation to replace Shaughnessy.
