Washington Redskins offensive tackle Trent Williams, the fourth overall pick in the 2010 NFL Draft, left Sunday's overtime loss to the Houston Texans late in the fourth with a left knee injury.

According to Jason Reid of the Washington Post, an MRI on Williams' knee showed no structural damage.

Williams does have a knee contusion and sprained toe, but that may not be enough to keep Williams out of next Sunday's game against the St. Louis Rams.

Redskins head coach Mike Shanahan is expected to provide an additional update during his 3pm ET press conference.
