LANDOVER, Md. (CBSDC) — Washington Redskins left tackle Trent Williams is scheduled to undergo an MRI after injuring his right knee in the first quarter of Sunday’s loss to the Cincinnati Bengals.

He came back in the game late in the second quarter and for a brief moment immediately after halftime before settling on the sideline for the duration of the game.

“I don’t know what it is as of now,” said Williams. “I haven’t looked at the replay. I just felt it give out on me.”

Washington’s offensive line struggled mightily in pass protection without Williams. Robert Griffin III was sacked six times and hurried countless others.

Williams, a first-round pick in 2010 and a critical offensive component, was replaced by Jordan Black.

His injury compounds the loss of projected starting right tackle Jammal Brown who remains on the PUP list following surgery in late August to correct a suspect hip.

NOTES: Crezdon Butler and Cedric Griffin also suffered hamstring injuries in the game.
