The Washington Redskins have placed linebacker Brian Orakpo and defensive end Adam Carriker on injured reserve.
The team replaced the two players Tuesday by promoting defensive end Doug Worthington from the practice squad and signing linebacker Markus White from Tampa Bay's practice squad.
Orakpo injured his left shoulder and Carriker hurt his right knee in Sunday's 31-28 loss to the St. Louis Rams.
Worthington was drafted in the seventh round by the Pittsburgh Steelers in 2010 and spent most of last season on the Redskins' practice squad.
White was a seventh-round pick by the Redskins last year and played in two games as a rookie. He was cut at the end of preseason last month.
The Redskins also signed defensive lineman Dominique Hamilton to the practice squad.
