Free agent cornerback Nolan Carroll is working out or the Redskins on Monday, Ian Rapoport of NFL.com (on Twitter) hears. Carroll was released by the rival Cowboys last week. 
The Cowboys signed Carroll to a lucrative three-year deal this offseason, but he did not appear to be a great fit in the summer and a Week 2 concussion sidelined him for multiple games. Dallas decided to cut ties with him after Week 5, a move that meant eating $4MM in guaranteed salary.
Carroll, 30, started in all 16 games for the first time in his career last year and managed one interception, ten passes defensed, and a forced fumble for the Eagles. Pro Football Focus graded him as the NFL’s No. 92 cornerback among 112 qualifiers, but not every evaluator agrees with that assessment.
The Redskins’ secondary has been ravaged by injuries this season. On Sunday, starters Josh Norman and Deshazor Everett did not dress while Bashaud Breeland, Fabian Moreau, D.J. Swearinger, and Stefan McClure all suffered injuries during the game.
If Carroll is healthy, he would be a logical addition for D.C. He might also be able to provide the Redskins with some intel in advance of their Oct. 29 game against Dallas.
