(Reuters) - Replacement quarterback Colt McCoy overcame a limping Tony Romo to lift the Washington Redskins to a 20-17 overtime victory over the red-hot Dallas Cowboys on Monday, snapping the home team's winning streak at six games.
McCoy, who was named as starter after filling in for a struggling Kirk Cousins last week, led Washington to a winning drive on the first possession of overtime with Kai Forbath booting the decisive 40-yard field goal.
Trailing by three, Dallas had one last chance to reply but failed to make it through the first set of downs with a bruised Romo tossing two straight incomplete passes to end the game.
Romo was taken out of the contest in the third quarter with a back injury but returned in the final minutes of regulation to try and lead an ultimately unsuccessful comeback.
It was the second straight win for the Redskins (3-5) while Dallas (6-2) lost for the first time since the season-opener.
McCoy was strong in his starting opportunity as he tossed for 299 yards and put Washington ahead 17-10 with a seven-yard rush early in the fourth. Dallas answered with backup QB Brandon Weeden, briefly taking over for Romo, finding Jason Witten on a 25-yard connection that sent the game into overtime.
NFL-leading rusher DeMarco Murray registered his eighth straight 100-yard running game for Dallas, compiling 141 yards on the ground along with 80 yards receiving in the defeat.
