The Redskins won the coin toss in overtime and began at their 18. Washington ran nine plays, including a 12-yard pass to Logan Paulsen and a 12-yarder to Gaffney, to set up a Graham Gano’s 52-yard field goal try at 9:27 that went wide right.
The Cowboys took over at their 42, picking up 14 yards on first down but later facing third and 15 at the Redskins’ 49. Romo completed a 26-yard pass to Dez Bryant to the 23, and two plays later Dan Bailey hit from 39 yards.
Dallas was on the move to start the final period, facing first and goal at the 7. Romo threw incomplete twice before scrambling out of the pocket, pump-faking to get linebacker Perry Riley to stop his advance and then completing a pass to Laurent Robinson in the middle left of the end zone with 14:43 to play to tie it at 17.
The Cowboys came back with passes of 12 and 13 yards from Romo to wide receiver Kevin Ogletree and backup tight end Martellus Bennett to move to their 39. After running back Felix Jones gained two yards on first and Romo threw incomplete on second, Witten found a seam on the left side of the field and turned an intermediate reception into a 59-yard touchdown with 8:48 to go.
On the Redskins’ ensuing play from scrimmage, Grossman tried to throw a deep ball to Armstrong as he was getting hit, but it wound up in the arms of cornerback Orlando Scrandrick at the Dallas 41. The Cowboys were unable to score any points despite good field position.
Washington took over at its 11-yard line with 5:35 to play. From there the Redskins got three long plays and a defensive holding call on third and two to reach first and 10 at the Cowboys 11. Grossman found Donte Stallworth in the corner on a fade route for a four-yard touchdown to tie the game with 14 seconds left and force overtime.
The Redskins got the ball to start the second half at their 23 and used a handful of big plays to get within scoring distance. The first was a 28-yard pass from Grossman to Gaffney to reach midfield, and two plays later, Grossman completed a 24-yarder to tight end Fred Davis.
Running back Ryan Torain lost two on first down, and Grossman threw incomplete a couple of times. Place kicker Graham Gano gave Washington a 17-0 lead with a 40-yard field goal with 11:40 to play.
The Redskins’ second possession of the half began at the Cowboys 34 following Brandon Banks’s career-long 55-yard punt return. But Washington netted only three yards on three plays, and Gano’s 49-yard field goal attempt went wide right.
The Cowboys got the ball at their 39 and marched down the field as the quarter expired. The drive included a seven-yard run by Murray on fourth and one and a 15-yard completion to tight end Jason Witten on second and 10 to the Redskins 18.
From there, running back Felix Jones caught passes of four and seven yards to set up first and goal at the 7 as the third quarter ended.
The Redskins began the quarter with quarterback Rex Grossman fumbling on third and two after getting hit by defensive end Jason Hatcher. Grossman fell on the ball, but the Cowboys took over at their 48 following a punt.
Dallas settled for a 37-yard field goal from Dan Bailey, and on the Redskins’ ensuing first snap, guard Tyler Polumbus was penalized for holding. A 17-yard completion to wide receiver Jabar Gaffney set up third and one, and Grossman tried a sneak.
The ball came loose in a pile at the line of scrimmage, and safety Barry Church picked it up at the 29 and ran to the 1. Shanahan challenged the call, and officials overturned it, allowing the Redskins to punt.
The Redskins got the ball back at the Cowboys 32 with 7:23 to go until halftime and Grossman eventually hit wide receiver David Anderson for a 22-yard pass the 6. On third and goal, Grossman kept it for a four-yard touchdown to cut it to 10-7 with 3:59 to play.
The Redskins then took the lead with 14 seconds left on a 16-yard touchdown pass from Grossman to Jabar Gaffney in the back of the end zone, capping a 43-yard drive that left them with their first lead since Week 4 against St. Louis.
The Cowboys got the ball to start the game and moved to the Redskins’ 35, but on third and seven, wide receiver Laurent Robinson was late coming out of his break, and quarterback Tony Romo’s throw fell incomplete.
Washington’s first possession began at its 20, and the first two play were end-arounds to Anthony Armstrong and Donte Stallworth. On third and six, tight end Fred Davis caught a short pass and tried to extend the ball for a first down, but safety Gerald Sensabaugh jarred the ball loose and recovered.
Redskins Coach Mike Shanahan challenged the ruling, but officials upheld the call, and the Cowboys took over at the Washington 24. Romo threw incomplete on first down, and running back DeMarco Murray gained two on the next play.
On third down, wide receiver Dez Bryant ran an out pattern just in front of the goal line, and Romo delivered a strike. Bryant had gotten behind cornerback DeAngelo Hall and safety Oshiomogho Atogwe and caught the ball as he spun just inside the front right pylon for a touchdown with 7 minutes 44 seconds to play.
The Cowboys had another scoring chance late in the quarter, but with Robinson open down the right sideline, Romo threw long, and the score remained 7-0.
