The Redskins, of course, are used to shuffling the offensive line, and it's how the team ultimately felt comfortable with making Roullier the starting center this season. He subbed in for Spencer Long last year and, despite dealing with his own injuries, showed enough on tape to take over the position.

"It is a challenge anytime we have anybody that has to move positions, or any guys that's new to the lineup, it's definitely a little learning curve to get them caught up to speed on how we do things," left tackle Trent Williams said. "But with Tony being a veteran, and knowing the offense inside and out, Chase kicking over to guard, those are two of the smarter guys in the offensive line room, so I think they'll be okay."

Switching back to guard isn't ideal as Roullier tries to gain more momentum and chemistry with quarterback Alex Smith under center, but he understands the value in being versatile.

"For the most part I was starting to feel comfortable at center, and I always had to have the mindset of the guy that was going to move over there if that happened," Roullier said. "So you know even the last couple games whatever I have to study as a guard, so it's something that's always in the back of my mind when I go do if I need to and I'm happy to do it. I loved playing guard in college, it's still a very fun position for me to go out there and do it."

The only hitch this week, Roullier said, took place on Wednesday during walkthrough, when he walked up to the line of scrimmage and began pointing out assignments, forgetting that was Bergstom's responsibility now.
