The Washington Redskins will be without three starting offensive linemen when the team travels to face the Tampa Bay Buccaneers on Sunday.

Left tackle Trent Williams (thumb surgery) was officially ruled out Friday, and guards Brandon Scherff (shoulder) and Shawn Lauvao (ankle) were both placed on injured reserve this week. Right tackle Morgan Moses (knee) was limited in practice Thursday and Friday. He is listed as questionable.

Washington Coach Jay Gruden did not have a full plan for a starting line after signing three new offensive linemen this week.

Ty Nsekhe and Moses will be the tackles, if Moses is healthy. Rookie Geron Christian will step in if Moses can’t go. Chase Roullier is slated to stay at center and Tony Bergstrom will play right guard. Jonathan Cooper seems to have the inside track to start at left guard.

“We’re hoping the experience that Jonathan has will help, and Bergstom’s played a lot,” Gruden said. “Obviously, Chase, and hopefully we get [Morgan] back. So, that’s still pretty solid, if you ask me. When you’re out there on the field, you’ll get a better gauge of how they’re doing. How we’re protecting. How we’re run blocking. How they’re handling the heat and the drives and the communication. Time will tell. I’m anxious to see it."

The team will also be without running back Chris Thompson (ribs), who has already missed three games. Cornerback Quinton Dunbar (shin) and wide receiver Jamison Crowder (ankle) were listed as questionable.

Dunbar sat out two games before returning against the Atlanta Falcons, but re-aggravated a nerve issue in his leg. He did not practice all week. Crowder has missed the last four games, but returned to practice on a limited basis Thursday.

Sunday’s game will also be the first since wide receiver Paul Richardson went on injured reserve with a shoulder injury. Maurice Harris is next in the rotation, with Michael Floyd and Brian Quick ready for additional snaps if Crowder misses another game.

The Buccaneers will be without defensive end Vinny Curry (ankle), running back Ronald Jones II (hamstring), cornerback M.J. Stewart (foot) and offensive lineman Evan Smith (hip/wrist).
