With their critical division game against the Cowboys just over 72 hours away, the Redskins held practice Thursday with four of their five offensive line starters sidelined.



Spencer Long (knees), Brandon Scherff (knee), Trent Williams (knee), and Morgan Moses (ankles) were all spectators as the line went through preparations. Only left guard Shawn Lauvao participated.



Of the four who were out, Jay Gruden indicated that Long, who has tendonitis in both knees, is the least likely to play on Sunday. “They’re all a concern but I’d say Long is probably the biggest concern,” he said. “I don’t know how long [he] will be out."

If Long can't go, rookie Chase Roullier will get his first NFL start.

Williams has played in each of the last two games after not practicing at all the week before. Moses has played through ankle injuries in the past but this time both of his ankles are sprained. It would not be surprising if both of them played, with that being sid.



That leaves Scherff as the question mark. Earlier this week Gruden said that Scherff was better off than they thought he might be after the initial diagnosis but his status remains up in the air.

There was some good news on the injury front. Cornerback Josh Norman, who has missed the last two games with a broken rib, practiced on a limited basis and Gruden hopes that he can get cleared to play against the Cowboys tomorrow. Gruden said that OLB Preston Smith (groin) is “feeling a lot better than we expected but we’ll see.” Smith could be active for the game and play a limited number of snaps.

Also out of practice was OT Ty Nsekhe, who is still recovering from a core muscle injury he suffered in Week 3. Limited were Norman, Smith, G Tyler Catalina (concussion), S Deshazor Everett (hamstring), LB Mason Foster (shoulder), S Stefan McClure (hamstring/knee), and CB Fabian Moreau (hamstring).

LB Zach Brown was listed as out on yesterday’s hypothetical practice report (the team held a walkthrough) with a back injury but he was a full go today.

The injury report with the game status for the injured players will be issued on Friday.
