With five games remaining this season, the Redskins are a long shot to make the playoffs with their current record at 5-6. They would practically need to win out, starting Thursday night against the Dallas Cowboys, to have a shot at a playoff berth in a very competitive wild-card race. Left tackle Trent Williams has been taking it week-by-week while playing through a right knee injury that will eventually require surgery, but he currently doesn’t have any intention of shutting it down even if Washington is eliminated.
