Moss, who has 24 catches for 297 yards this season, is expected to be replaced by James Thrash in the lineup. Thrash has three catches for 16 yards this season.
Another Redskins wideout, Antwaan Randle El, is active for the game despite a nagging hamstring injury.
Linebacker Marcus Washington, who also has a hamstring injury, is inactive for the Redskins and will miss his fourth game since Week 5.
The Redskins are the only team in the NFL without a touchdown reception by a wide receiver this season, and Moss and Randle El are the only wideouts who have been somewhat productive.
Moss has struggled since missing the Oct. 7 game against Detroit with a groin injury, with only 12 catches for 98 yards over the previous four games.
Eagles running back Correll Buckhalter was inactive with what the team would only say was an illness. He's second on Philadelphia with 40 carries for 193 yards rushing.
