The Redskins swapped out one fourth-round linebacker from Texas with another Monday.
After putting Keenan Robinson on injured reserve with a torn right pectoral muscle, the Redskins signed Roddrick Muckelroy to replace him.
Robinson was their own fourth-rounder this year. Muckelroy was the Bengals fourth-rounder in 2010.
“We liked him in the draft, and we were glad he was out there,” coach Mike Shanahan said, via Rich Campbell of the Washington Times. “When you lose a player and you get a guy like him to come into your system, you feel pretty fortunate.”
Muckelroy spent parts of three seasons with the Bengals, where he was primarily a special teams player, but missed all of 2011 with a torn Achilles.
Shanahan said Robinson would need surgery, and would face a five-month recovery.
