With their secondary dealt hit by injury once again, the Washington Redskins have signed veteran cornerback Cary Williams, a person with knowledge of the situation confirmed.

An eighth-year veteran, Williams appeared in 10 games for Seattle this year, starting all of them. He had 46 tackles and four pass breakups.

A seventh-round pick of the Tennessee Titans out of Washburn in 2008, Williams also has played for Baltimore and Philadelphia. Last spring, he signed a three-year, $18 million contract with Seattle with $7 million guaranteed.

However, the 6-foot-1, 190-pound Williams struggled to adjust to the Seahawks’ system and was benched in Week 11.

Speaking about Williams at the time, Seattle coach Pete Carroll said, “[Williams] has been playing hard and tough, and trying to get it done and figure it out. But he’s new to the system and some of the principles. You’ve just got to keep coming back to it and all that. So he’ll work really hard at it.”

However, Seattle cut Williams the following week.

Washington needs help in the secondary after losing rookie defensive back Kyshoen Jarrett to a neck injury that has resulted in nerve damage and a reduction in strength in his right shoulder. Jarrett, who has started six games while lining up at nickelback and safety, already has been ruled out for Sunday’s playoff game against the Packers. Meanwhile, fellow backup cornerback Dashaun Phillips also suffered a neck injury in the season finale at Dallas and was carted off, although his injury is believed to be less severe.

Williams could see significant playing time on Sunday with Washington lacking a proven cornerback behind Bashaud Breeland and Will Blackmon.

The move was first reported by ESPN.
