The Eagles ended up scoring the final 30 points of Sunday's game in North Texas to crush the Cowboys 37-9.
They didn't start off so hot though.
In fact, the Eagles were down 9-7 at halftime, so when they got the ball back to start the second half, it was a pretty important drive.
On first down, Jay Ajayi ran for 8 yards. On the next play, he went 1 yard.
That set up a 3rd-and-1 and one of Doug Pederson's best and gutsiest play calls of the game. Out of an unusual look, the Eagles ran a screen play to Brent Celek that picked up 28 yards and helped them continue a scoring drive.
"It was a great call," offensive coordinator Frank Reich said. "Great feel and call from coach. We're meeting the night before. He and I always meet on Saturday night, the night before (the game) for an hour, hour and a half, just going through the call sheet, talking about what he's going to call, why he's going to call it. And we're bouncing things back and forth.
"That was one I knew he was going to call. He was just waiting for the opportunity to call that play. Had a good sense."

Let's take a closer look at the play:
Here's a look just before the snap. The Eagles are using a "tackle over" formation. You'll notice Lane Johnson is lined up inside Halapoulivaati Vaitai and Celek (circled) is lined up as the right tackle.
The Eagles didn't motion into this look. They came out in it, with all three tight ends to the right side of the line. Trey Burton is lined up like a fullback. When the Cowboys see this, they load up that side of the defensive line, prepared for a run on 3rd-and-short.
Carson Wentz takes the snap and begins to roll right for the play fake. Celek (still circled in red) engages and holds his block for a couple seconds. "Celek did a great job of selling it and good execution," Reich said.
With the play going right, the Cowboys' linebackers are going with it.
Here's the other angle just after Celek releases his block. The Cowboys' corner on the defensive right is blitzing, but with Wentz rolling right, he won't have enough time to get to him.
Marcus Johnson, who was the outside receiver on the offensive left is running a go route, which will drive the safety out of the play. That leaves a ton of space open on that side of the field.
It takes a perfect throw from Wentz and it wasn't easy to get off. Because of the blitzing corner, he needs to throw off his back foot and will need to loft the ball over the defensive end, who never gained an inch on Vaitai.
At the point of the catch, Celek would have already had the first down. He has the ball for a short gain but rumbles ahead into open space for a 28-yarder, his longest catch of the last two seasons.
This was a play the Eagles practiced during the week, but Reich said it looked just OK. According to Reich, those types of plays usually look better live in games than they do in practice.
It certainly worked.
"You want to hear defensive players swear," Chris Collinsworth said on the NBC broadcast, "that play probably does it more than any other."
