Eagles running back Darren Sproles will now miss Sunday night’s showdown with the Cowboys at the Linc.

He aggravated his hamstring injury in practice yesterday, sources told ESPN’s Adam Schefter.

Coach Doug Pederson said he expected the running back to play Sunday in his first game since Week 1.

Sproles hurt the hamstring in practice leading into Week 2 and has missed the past seven games.

The Eagles had hoped Sproles could resume punt-return duties and rejoin a backfield currently being led by Wendell Smallwood and Corey Clement. Philadelphia ranks 18th in rushing yards per game this season with 106.6.

DeAndre Carter had been returning punts in Sproles’ absence but was waived Tuesday and claimed by the Houston Texans on Wednesday.
