Aaron Wilson of ProFootball.Scout.com reports the Redskins worked out veteran offensive tackle Chester Pitts, according to a league source.
Pitts, 32, is a former Texans starter who started five games last season for the Seahawks.
A former second-round draft pick from San Diego State, Pitts underwent microfracture knee surgery after hurting his right knee two years ago when he was with the Texans.
