LOUDOUN COUNTY, Va. – For the third time in less than a month, the Redskins have a new backup plan.

After quarterback Colt McCoy fractured his fibula in Monday’s loss at Philadelphia, the Redskins signed QB Josh Johnson on Wednesday to serve as Mark Sanchez’s backup.

Johnson, selected in the fifth round (160th overall) of the 2008 NFL Draft, has been with Tampa Bay, San Francisco, Cleveland, Cincinnati, New York Jets, Indianapolis, Buffalo, New York Giants, Jacksonville, Houston and Oakland. However, the 32 year-old has not thrown a pass in a regular season game since 2011 with the Buccaneers.

When Tampa drafted the University of San Diego product in 2008, current Redskins head coach Jay Gruden served as offensive assistant with the Bucs. Johnson appeared in two games for the Bengals in 2013. Gruden was the offensive coordinator of that team.

The Redskins also announced the signings of offensive linemen Demetrius Rhaney and Zac Kerin, and defensive end Marcus Smith. In corresponding moves, the team placed offensive lineman Jonathan Cooper, receiver Trey Quinn, and cornerback Quinton Dunbar on injured reserve.
