ARLINGTON, Texas (AP) - Dwayne Harris returned a punt 86 yards for a touchdown and set up another score with a 90-yard kickoff return for the Dallas Cowboys, who led the Washington Redskins 21-16 after three quarters Sunday night.
There were flags along the Redskins sideline after Harris' punt return with 2:26 left in the first half. But the penalty was for someone not in uniform on the Redskins bench inadvertently bumping into an official during the play. The score stood and the unsportsmanlike conduct penalty was enforced on the kickoff.
Another Washington penalty had provided Harris with a second chance at a return. The Redskins were flagged for illegal motion, and Dallas accepted the penalty that forced them to kick again and set up the fifth-longest punt return in Cowboys history.
After Kai Forbath's third field goal for Washington in the third quarter, Harris took the ensuing kickoff 5 yards deep in the end zone. He took off down the right sideline - again racing past the Washington bench - before finally being pushed out of bounds by E.J. Biggers at the 15.
Two plays later, Tony Romo threw a 15-yard TD to rookie Terrance Williams, who made a nifty catch to get both feet in bounds in the back corner of the end zone.
The Redskins closed to 21-16 when Alfred Morris busted loose for a 45-yard touchdown run. That came a play after safety Barry Church was penalized for unnecessary roughness when he hit Robert Griffin III as the quarterback scrambled out of bounds.
That was the second time in the third quarter that Church was penalized 15 yards for a hit on Griffin along the sideline.
DeMarco Murray ran 4 yards for a touchdown on Dallas' opening drive, but left early in the second quarter with a sprained left knee.
The Cowboys also lost defensive end DeMarcus Ware before halftime because of a right quad injury.
Redskins linebacker Bryan Kehl left with a sprained left knee, and cornerback David Amerson was ruled out after sustaining a concussion.
Forbath kicked a 32-yard field goal on the final play of the first half. He also had a 20-yarder on Washington's first drive of the game and the 33-yarder in the third quarter.
After the Cowboys scored on their first possession for the fifth time in six games this season, Washington responded by going 78 yards on 13 plays in more than 7 1/2 minutes. The Redskins had to settle for Forbath's field goal after Griffin came up short on a third-and-9 scramble.
When the teams played in the season finale last December at Washington, it was a winner-take-all game for the NFC East title. The Redskins won that one, part of a seven-game winning streak during which they beat the Cowboys twice.
Philadelphia won at Tampa Bay earlier Sunday to move to 3-3 in the NFC East. Dallas, which came in with a two-game losing streak, needed a win to match the Eagles for the division lead.
Washington lost its first three games this season, but won at Oakland before its bye last weekend. Griffin, returning to Texas where he won a Heisman Trophy at Baylor, had said he felt rejuvenated after the break and looked it.
RG3 threw a 19-yard pass on his first snap and ran for 15 yards on the next play. He got stopped at the 2 on his third-down scramble. He was 3-of-4 passing for 45 yards on the opening drive, the lone incompletion a drop by running back Alfred Morris that likely would have been a touchdown.
