Right tackle Tyler Polumbus (74) and the Redskins’ offensive line break the huddle against Philadelphia last month.

The Washington Redskins are expected to have right tackle Tyler Polumbus back in the lineup after a concussion sidelined him last week. But safety DeJon Gomes will be inactive despite practicing on a limited basis all week long.

Polumbus practiced off and on in a limited capacity the last two weeks but was held out of action last week, and Maurice Hurt started in his place. Gomes has split time with Reed Doughty and Jordan Pugh at free safety this season.

For only the second time this season, quarterback Rex Grossman will dress. It’s the first time all season that the Redskins will have three active quarterbacks.

Also inactive for the Redskins are receivers Brandon Banks and Dezmon Briscoe, linebackers Roddrick Muckelroy and Vic So’oto and offensive linemen Tom Compton and Adam Gettis.

The Cowboys will be without nose tackle Jay Ratliff, running back Phillip Tanner, center Kevin Kowalski, guard David Arkin, guard Robert Callaway, tackle Darrion Weems and guard Ronald Leary.
