The Washington Redskins have placed defensive linemen Ma'ake Kemoeatu and Phillip Daniels on injured reserve. Kemoeatu said Wednesday he has a left shoulder injury that will probably require surgery. Daniels has abdominal, groin and hamstring injuries. The Redskins replaced the pair by signing linebacker Rob Jackson and defensive lineman Darrion Scott. Jackson was promoted from the practice squad, and Scott was one of the last cuts of training camp. Source: cbssports.com
