FRISCO, Texas -- Eagles coach Doug Pederson's "we're gonna win that football game" comment on Monday has not been much of a topic of discussion inside the Dallas Cowboys' locker room as they get ready to play Philadelphia on Sunday, but defensive end DeMarcus Lawrence will not forget it.

"Tell him to come on. We ready," Lawrence said. "Can he play the game? So he might want to shut his ass up and stay on the sideline. He can't play the game for them. The Eagles got to play them and he's supposed to sit on the sideline and do whatever he wants to do. But he can't play the game for them, so we'll see."

Lawrence called Sunday's game a "must-win" with Dallas on a three-game losing streak. He referred back to last year, when the Cowboys had a slow start to the season and rallied to reach the playoffs.

"We done seen hell and dug out of the pits of it," Lawrence said. "We was 3-5 last year and y'all were asking these same questions. Like, what is it to fear? Like, we all men. We already know what we got to do. We're going to go and show it and prove it."

Lawrence is no stranger to strong comments. Leading into last year's meeting against the New Orleans Saints, he said the Cowboys' defense had to "choke their ass out." The Cowboys responded with a 13-10 win.

Lawrence, who missed the offseason program and training camp because of shoulder surgery performed a few days after he signed a five-year, $105 million contract in April, has 2.5 sacks this season and is playing just 63.2% of the snaps. He played in 71.8% last year and will play more Sunday.

"You don't got to worry about this week," Lawrence said. "Doug Pederson already done called us out, so y'all know what it is. Thank y'all."
