UPDATE: Per the Redskins official site, Williams is officially listed as having a sprained knee.
The Redskins can ill-afford to lose any offensive linemen, particularly rookie LT Trent Williams.
Williams suffered what initially looks to be a left knee injury late during the fourth quarter on Sunday against the Texans. He stayed down on the field for several minutes as trainers checked and tested his left knee, and had to be helped off the field.
Stephon Heyer replaced Williams, and on his first play was called for holding that negated a 22-yard completion from Donovan McNabb to Santana Moss.
Losing Williams, the fourth overall pick in the draft who drew rave reviews for his performance against the Cowboys in Week 1, would be a big loss for the Redskins.
