Washington Redskins starting free safety Oshiomogho Atogwe sat out Wednesday afternoon’s practice with a knee injury, according to the team’s report.

Atogwe was limited by a hamstring pull during the preseason, but has played in all five of the Redskins’ regular season games. On Sunday, he recorded his first interception of the season, eight tackles and a sack.

According to the injury report, backup cornerback Byron Westbrook was limited by a hamstring injury.

Wide receiver Anthony Armstrong (hamstring), cornerback Phillip Buchanon (neck) and running back Tim Hightower (shoulder) all practiced fully after being limited last week and not playing on Sunday.

The Redskins also were without guard Kory Lichtensteiger, who has been placed on injured reserve with torn knee ligaments; tight end Chris Cooley, who on Wednesday had surgery to repair his broken left index finger; and tackle Trent Williams, who is expected to miss at least two weeks with a high ankle sprain.
