The Oakland Raiders put the outside linebacker Sio Moore, on injured reserve Tuesday after he missed Sunday's loss at Kansas City. He had a hip issue come up during practice last week and was ruled out of the game. A third-round pick in 2013, Moore had played well this season. He finished with 90 tackles. He is the fifth Oakland defensive starter to go on injured reserve this season. A sixth safety Usama Young, who replaced Tyvon Branch when he was put on IR, also was put on injured reserve. The Raiders have just four linebackers on the roster. Ray-Ray Armstrong made his starting debut at Kansas City, in place of Moore. Oakland signed cornerback Chance Casey off San Francisco's practice squad to take Moore's place on the roster. Casey was on Oakland's practice squad last season.
