Trying to win an NFC East game this season. The Washington Redskins stayed home for a Week 16 Showdown against the Dallas Cowboys. In the First Quarter the Cowboys Strike first with Tony Romo throwing a 4-yard Touchdown Pass to Roy Williams. In the Second Quarter Dallas Struck again with Marion Barber running a 3-yard Touchdown. While in the 4th quarter  Shaun Suisham made a 23-yard Field Goal. With the loss, Washington not only fell to 4-11, but failed to win a single game within their division (0-6), failed to win consecutive games in a season for the first time since 2004, and had their first shutout loss since October 30, 2005 to the Giants 0-36, and their first home shutout loss since December 14, 2003, also to the Cowboys.
