Washington sustained the injury in the team's preseason finale. He spent the week practicing in a limited role. He projects to backup Akiem Hicks, and provide defensive line depth if he can take the field Sunday.
Washington was forced to exit Thursday's game against the Browns due to a knee injury, his return is questionable.
Washington's injury was not specified beyond being a knee issue, so the severity is unknown at this point. He recently dealt with a quadriceps injury and the collective injuries make it likely the team sits him down for the remainder of the game, despite the questionable designation.
Washington is dealing with injuries to both his ankle and knee, but that hasn't kept him from finding a way onto the practice field. Even if he is unable to practice fully, it is a good sign that the 26-year-old is able to participate in some drills. How well Washington holds up the rest of the week will likely shed light on his status for Week 1.
