Dak Prescott threw three touchdown passes during a game with few flaws as the Dallas Cowboys defeated the Washington Redskins 31-21 on Sunday afternoon at FedEx Field in Landover, Md.

Prescott completed 26 of 30 passes for 269 yards with one interception, complemented by running back Ezekiel Elliott's 111 rushing yards.

Prescott, who began the season with a stellar outing a week earlier against the New York Giants, has the Cowboys off to a 2-0 start with a pair of NFC East Division victories.

Washington's Case Keenum was 26 of 37 for 221 yards with two touchdowns.

Prescott's first touchdown went for 51 yards to Devin Smith, who made his first reception of the season on the scoring play. Smith broke away from coverage for what became a relatively easy touchdown catch on his way to a game-high 74 receiving yards.

The Cowboys, taking advantage of Washington defensive penalties during the drive, scored with nine seconds remaining in the first half on Prescott's 2-yard toss to tight end Jason Witten.

In the third quarter, Prescott's 10-yard touchdown pass to Amari Cooper helped the Cowboys stretch their lead to 21-7.

Washington (0-2) briefly threatened as Paul Richardson's 9-yard TD reception from Keenum came with 4:30 to play in the third quarter.

Dallas scored the first 10 points of the fourth quarter, first on Brett Maher's 25-yard field goal and then on Elliott's 2-yard run.

Elliott finished with 23 carries, capped by a 27-yard run on the game's last possession.

Rookie Terry McLaurin's 1-yard touchdown catch from Keenum came with 2:17 to play.

Earlier, the Redskins took advantage of favorable field position only once in the first half. Adrian Peterson ran 1 yard for the game's first points. That scoring chance was set up by safety Montae Nicholson's interception, giving the Redskins the ball at the Dallas 38.

It took the Redskins 10 plays to cover the 38 yards.

Peterson, who was inactive for the opener a week earlier, finished with 25 rushing yards on 10 carries.
