Foles sustained a concussion in a 17-3 loss to Dallas on Oct. 20. It was his second start filling in for Michael Vick, who re-injured his left hamstring in the first half of a 15-7 loss to the New York Giants on Sunday.
Matt Barkley finished off both games, and offensive coordinator Pat Shurmur says the rookie will share first-team snaps with Foles in practice.
Vick's status remains day to day, though coach Chip Kelly already said it's unlikely he'll play at Oakland (3-4) this week.
The Eagles (3-5) have lost two in a row and are one game behind the Cowboys (4-4) in the NFC East.
