Maurice Hurt could be in line to make a second straight start for the Redskins at right tackle Sunday, with Tyler Polumbus still sidelined by a concussion.

Hurt started at that spot in last weekend’s triumph at Philadelphia, one week after Polumbus suffered his concussion during a win at Cleveland. Polumbus missed Wednesday’s practice and still must be cleared by doctors to resume practicing and playing. If that doesn’t happen, the Redskins again would rely on Hurt in Sunday night’s game against the Dallas Cowboys with the NFC East title at stake.

Coach Mike Shanahan praised Hurt’s play against the Eagles. Hurt said Wednesday he’ll be ready to face the Cowboys if needed and believes he would feel more at home at the position if he makes a second start there.

“I think I’ll be more comfortable than I was the last week just because the amount of reps I played this last weekend and the experience I got at the position,” Hurt said after Wednesday’s practice. “I think I’ll be more comfortable this week than I was last week.”

Hurt started at guard in the second half of last season and only began getting regular practice-field snaps at tackle, he said, in recent weeks. He said he had an idea last Friday that he might start in Philadelphia but didn’t know for certain until Saturday.

“There’s a lot I can improve on,” Hurt said. “But I think all in all, I did okay. I’m my worst critic. So I feel like I can definitely improve and get a lot better.”

He became the first backup forced into starting duty on the offensive line all season. Until last weekend, the Redskins had started the same five offensive linemen—left tackle Trent Williams, left guard Kory Lichtensteiger, center Will Montgomery, right guard Chris Chester and Polumbus at right tackle—in every game this season.

“As the game went on, I think I got more comfortable,” Hurt said. “With the guys beside me helping me and the confidence of the rest of the guys on offense and on defense–guys were encouraging me to do well. All those things go along with helping your comfort level.”
