Nick Foles has a concussion and Michael Vick is still recovering from a hamstring injury, leaving the Philadelphia Eagles uncertain of a starting quarterback next week.

Foles was injured when he was sacked by George Selvie and Jarius Wynn on the final play of the third quarter in a 17-3 loss to Dallas on Sunday. Foles struggled against the Cowboys, completing just 11 of 29 for 80 yards with no touchdowns or interceptions.

Vick has missed the last 2½ games. If neither can play against the New York Giants, rookie Matt Barkley would make his first career start.

Barkley threw three interceptions in the fourth quarter in his first NFL action.
