Gibson (toe) didn't participate in Thursday's walk-through practice, John Keim of ESPN.com reports.
Gibson has been playing through a stress fracture in his shin for most of the season, but it's a toe injury that has kept him off the field for Washington's first two practices of Week 16. The 23-year-old appeared to pick up the injury during Tuesday's 27-17 loss to the Eagles, but he was able to check back into the contest and compiled 65 yards from scrimmage and a touchdown on 21 touches (15 carries, six receptions). Washington may just be exercising some extra caution with Gibson with the Football Team facing a quick turnaround for its Week 16 game in Dallas, but the running back will likely need to practice in some capacity Friday to have a chance to play Sunday. With J.D. McKissic (concussion) on injured reserve, Jaret Patterson is the next man up for touches behind Gibson in the backfield.
