The Redskins injury report contained some bad news along the offensive line as on starter missed practice and another starter and his backup were limited.The offensive line starter who was out was left guard Maurice Hurt, who was sidelined with a knee injury. He played all of Sundays game in Miami but apparently an issue popped up after that.Starting right tackle Jammal Brown, who missed the Miami game with a groin injury, was limited in practice. Sean Locklear, who started in Browns place, was limited with an ankle injury.If Brown and Locklear are unable to play on Sunday against the Cowboys, it seems likely that Tyler Polumbus, who joined the team last week, would get the nod at right tackle. The other option would be rookie Willie Smith.Mike Shanahan said that the team is evaluating options at guard. After left guard Kory Lichtensteiger went out for the year with a knee injury on Oct. 16 against the Eagles, center Will Montgomery moved into Lichtenstiegers spot and Erik Cook played center. That lineup continued until the game against the 49ers when Hurt came in at guard and Montgomery moved back to center.Also not practicing were linebackers London Fletcher (ankle) and Keyaron Fox (infection), safety LaRon Landry, and wide receiver Niles Paul.Free safety Oshiomogho Atogwe, who has missed the last two games, participated fully in practice.
