While much of the attention this week will surely focus on uncertainty at the Redsins’ quarterback position, the team faces even more questions along its offensive line.

With guard Kory Lichtensteiger lost for the year and left tackle Trent Williams likely out at least a week, the Redskins will have to shuffle bodies and will be lacking in depth as they prepare for Carolina.

“Any time you lose a couple guys, there’s always depth that’s a concern, sure. That’s one of those positions,” Coach Mike Shanahan said Monday.

Shanahan wasn’t ready to commit to how the starting five might look this Sunday against the Carolina Panthers. The Redskins finished the Philadelphia loss with eighth-year lineman Sean Locklear at left tackle, starting center Will Montgomery at left guard, first-year interior lineman Erik Cook at center, veteran Chris Chester at right guard and Jammal Brown at right tackle.

“We’ll talk about that a little bit later on in the week,” Shanahan said

Shanahan said Lichtensteiger tore both his ACL and MCL and will be placed on injured reserve. The coach said Lichtensteiger likely will undergo surgery within the week.

“It’s big,” Shanahan said of the loss. “Kory was playing at a very high level.”

Lichtensteiger’s spot on the 53-man roster will go to Maurice Hurt, the Redskins’ seventh-round draft pick out of Florida who spent the first six weeks of the season on the practice squad.

If the Redskins don’t make another roster move, they’ll go into this Sunday’s game with a shallow and inexperienced bench. Their only two reserves will be Hurt and undrafted free agent Willie Smith, neither of whom has played a single NFL snap.

Among the starting five, Shanahan must decide: Will Brown stay on the right side or slide over to the left, where he earned his way into two Pro Bowls while playing in New Orleans? And does he stick with Cook at center and play Montgomery at guard?

Brown’s preferred position is left tackle, but he said he wasn’t sure which way Shanahan might go. “That’s a possibility,” Shanahan said of moving Brown.

Of Cook, a seventh-round draft pick in 2010 out of New Mexico, Shanahan said: “I thought Erik Cook played fairly well for his first game.”
