PHILADELPHIA (AP) - Eagles quarterback Michael Vick did not practice on Wednesday, but has not yet been ruled out of Sunday's game vs. the Washington Redskins.

Vick suffered a concussion in the second quarter of a 38-23 loss to the Dallas Cowboys four days ago. Backup Nick Foles, a rookie, took the first-team snaps at Wednesday's practice and would make his first career start should Vick not be able to play.

Foles was 22 of 32 for 219 yards with a touchdown and an interception in relief of Vick. Those numbers weren't enough to help the Eagles avoid their fifth straight loss, a first in coach Andy Reid's 14 seasons.

Vick's headaches are subsiding, Reid says, but the veteran still needs to complete the mandated concussion testing this week.

Philadelphia and Washington, both 3-6, are tied for last place in the NFC East.
