– Amari Cooper's impact on Dak Prescott has been dramatic. The new No. 1 receiver for the Dallas Cowboys shook up the NFC East race, too.

Prescott threw his third touchdown pass to Cooper on the first possession of overtime, and Dallas took a big step toward the division title with a 29-23 victory over the Philadelphia Eagles on Sunday.

On third down, Rasul Douglas tipped a pass into the air by getting inside the slant route, and Cooper grabbed it and had a clear path to the end zone from the Philadelphia 7 for a 15-yard score. The Cowboys used almost all of the 10-minute OT, scoring with 1 minute, 55 seconds remaining.

"I knew I had the slant route there, but I knew he would sit on it," said Cooper, who had a career-high 217 yards on 10 receptions. "Itried to sell the fade. It didn't really work, but I just stayed with the ball and there you have it."

Said Douglas: "I played it perfectly. I couldn't get the other hand in there to get the pick. I tried to bat it down."

By winning the third OT game in the past four seasons at A&T Stadium between these division rivals, the Cowboys (8-5) won their fifth game in a row and took a two-game lead over the defending Super Bowl champion Eagles (6-7) and Washington with three games left.

Carson Wentz threw for three touchdowns, including a pair of tying scores in the fourth quarter. But he never got a chance in overtime because Prescott engineered a 13-play, 75-yard drive.

Prescott overcame three turnovers to set career highs in completions (42), attempts (54) and yards passing (455).

"Helpless feeling," Wentz said. "I've got a lot of lot of confidence in the defense. They were making plays today. We just didn't do enough early offensively, and that cost us."
