Answer based on context:

Hoping to end the two-game skid from their tough losses to the New York Giants and San Diego Chargers, the Cowboys went to the Superdome to take on the undefeated New Orleans Saints. The Cowboys took the lead in the first half by scoring two touchdowns with a 49-yard pass from Tony Romo to Miles Austin and a 3-yard touchdown run by Marion Barber. Outside linebacker DeMarcus Ware made a big play as he sacked Saints quarterback Drew Brees and caused the ball to be fumbled. Anthony Spencer recovered the ball to put it in Dallas' hands. The Saints only points of the half were from a 43-yard field goal by Garrett Hartley. In the second half, the Cowboys scored their only touchdown in the third quarter with a two-yard touchdown run by Marion Barber. Finally in the fourth quarter New Orleans got a touchdown when running back Mike Bell scored from one yard out to make a 24-10 Dallas lead. Drew Brees also made a 7-yard touchdown pass to wide receiver Lance Moore. After that, Nick Folk attempted a 24-yard field goal, but the kick was no good. With a big advantage to take the lead as the clock was expiring, the Saints were driving for the game-tying score, but DeMarcus Ware made his second sack on Drew Brees, which again caused the ball to be fumbled. This time the ball was recovered by nose guard Jay Ratliff. With the ball in possession, Dallas took a knee to conclude the game. With a huge win over the once-undefeated Saints, the Cowboys extended their chances to make the playoffs and ended a two-game losing streak. They improved their record to 9-5.
