ARLINGTON, Texas -- Rookies Dak Prescott and Ezekiel Elliott keep winning for the Dallas Cowboys, even with Kirk Cousins setting records for the Washington Redskins.Prescott accounted for two touchdowns , Elliott ran for a pair of scores and the Cowboys extended their franchise regular-season record with a 10th straight victory, beating the Redskins 31-26 on Thursday.Prescott tied Don Merediths club quarterback record from 50 years ago with his fifth rushing TD and the NFL-leading Cowboys (10-1) won despite 449 yards passing and three touchdowns from Cousins, the first Redskins quarterback with two 400-yard games in a season.You know youre talking to someone who knows how hard this is to win 10 games in a row, and I do, Cowboys owner and general manager Jerry Jones said. I know how were getting it done, and were getting done by hard work and Daks a great example.The Redskins (6-4-1) got swept by their NFC East rival, and the defending division champions fell 3 1/2 games behind Dallas with five games left. It was their seventh loss in eight tries on Thanksgiving against Cowboys, who had never won more than eight straight in the regular season.Weve been in third place for a while, so we have to understand where we are what its going to take to get an opportunity to come back here in the future, Washington coach Jay Gruden said. The last five games of the year are critical.Elliott, the NFL rushing leader, had the fourth score on five straight second-half touchdown drives between the two teams with a 1-yard run for a 31-19 lead midway through the fourth quarter. The 21-year-old had 97 yards to give him 1,199 for the season.After getting 43 yards on the first Dallas possession, Elliott had just 13 yards before a 21-yarder to start Dallas last TD drive. It was the second straight week he finished with 97 yards after some difficulty in the first half.Over time, you keep running the football, youre going to wear them down, Dallas coach Jason Garrett said. He made some big runs late that were critical. It really broke their back.The Cowboys had an eight-game streak with at least 400 yards snapped, finishing with 353. But Dallas answered with touchdowns each time the Redskins got within a score on Cousins passes of 5 yards to Jordan Reed and 67 yards to DeSean Jackson , who had 118 yards receiving.After Cousins second scoring toss to Reed, an 8-yarder with 1:53 remaining, Dustin Hopkins onside kick went out of bounds. The Cowboys ran out the clock.The way Dallas was able to come back and put points on the board in those situations is part of the reason why they are such a good football team, said Cousins , who was 41 of 53 and finished 8 yards shy of his career high.As an offense, whenever we got the football, it was pretty much the same. Move the football, put points on the board, make good decisions and manage it well.Cousins took the Washington career lead with his third 400-yard game and became the first Redskins quarterback with consecutive 350-yard games since Jay Schroeder in 1986. He had 375 last week against Green Bay.Reed had 10 catches for 95 yards after missing most of the first half when he injured his left shoulder leaping for a pass over his head in the end zone.Prescott was 17 of 24 for a season-low 195 yards and one touchdown, a toe-tapper to Terrance Williams . He had eight carries for 39 yards, including a career-long 18-yarder. Dez Bryant led Dallas with 72 yards on five catches.BACK TO THE PACKUndrafted rookie running back Robert Kelley of the Redskins was held to 37 yards on 14 carries a week after getting a career-high 137 yards with three touchdowns against the Packers. He was averaging more than 100 yards per game the previous three.SUN FIELDThe late-afternoon sun shining through the glass doors on the west side of the stadium was an issue in the opener when Dallas tight end Jason Witten admitted that
