PHILADELPHIA (CBS) — Our old friend DeSean Jackson will miss Sunday’s game against the Eagles with a hamstring injury, Redskins coach Jay Gruden announced on Friday.

Redskins cornerback DeAngelo Hall and inside linebacker Perry Riley were also ruled out for Sunday’s game. If starting cornerback Chris Culliver (questionable) also misses the game, Washington will be very thin at that position.

Jackson injured his hamstring in the Redskins’ Week 1 game loss vs. the Miami Dolphins and has not played since. ESPN reporter Britt McHenry reports that a source told her Jackson could possibly be out longer than expected.

The 28-year-old wide receiver joined the Redskins after being released by the Eagles, following the 2013 season. Last season, Jackson caught nine balls for 243 yards and one touchdown in two games against the Eagles. Jackson and the Skins spoiled the Eagles’ playoff hopes beating them 27-24 at FedEx in Week 16.
