The Redskins’ starting tackles are now bookends, in a bad way.

With right tackle Jammal Brown already missing due to a hip injury, left tackle Trent Williams is out with a foot injury suffered in Buffalo on Thursday night.

“He has a bone bruise,” coach Mike Shanahan said, via comments distributed by the team. “He’s pretty sore right now. We’ll have to play it day-by-day. I know it’ll be a few days.”

Shanahan said it’s “wait and see” as to whether Williams will play in the team’s second preseason game, next Saturday at Chicago.

“It’s always disappointing when somebody goes down, but it’s the nature of the game,” Shanahan said. “That’s why you build depth. Like we talked about at the beginning of the year, we got a few [offensive linemen] in the draft, got a couple in free agency, so we have a little bit more depth than we had a year ago. And it’s a good thing we do.”

He’s right. Because they have a young franchise quarterback who needs to be protected.
