The Redskins' fourteenth game was an NFC East rivalry rematch against the Cowboys at Cowboys Stadium. In the first quarter the Redskins trailed early with kicker David Buehler hitting a 42-yard field goal, followed by QB Jon Kitna throwing a 3-yard TD pass to WR Miles Austin; then Buehler made a 20-yard field goal to put Dallas up 13-0. The lead was narrowed when QB Rex Grossman completed a 19-yard TD pass to RB Ryan Torain, but fell further behind with Kitna making a 14-yard TD pass to TE Jason Witten, followed by RB Tashard Choice getting a 3-yard TD run. The Redskins replied with Grossman getting a 10-yard TD pass to WR Santana Moss, but the Cowboys scored again when Buehler got a 20-yard field goal. Washington managed to tie the game with Grossman finding Moss and Cooley on a 5-yard TD pass (With two successful 2-point conversions as Grossman passed to Cooley and Sellers). The Redskins couldn't get any further after Buehler made a 39-yard field goal, settling both records at 5-9.
