The Eagles only have 52 men on the roster due the trade of veteran NT Isaac Sopoaga earlier in the week. They didn't sign anyone to fill the final open roster spot yet.
Michael Vick is obviously inactive because he's still injured. Nick Foles starts in his place.
Here is the full list of Eagles inactives:
Michael Vick - Hamstring injury.
Jake Knott - Hamstring injury.
Matt Tobin - Depth OL.
Dennis Kelly - Depth OL.
Matthew Tucker - Depth RB.
WR B.J. Cunningham - Depth WR.
