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 without Williams in pass protection. Robert Griffin III was sacked six times and hurried countless others.
Williams, the team’s starting left tackle, 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. Brown must sit out at least the first six weeks of the season after the PUP designation.
