Vick was knocked on his back in the second quarter by linebacker Ernie Sims on an incomplete pass and was slow to get up. He headed for the locker room and rookie Nick Foles started warming up. Vick, however, may have been injured on the previous play when he was driven from behind head-first into the ground by tackle Jay Ratliff.
Vick did not talk to reporters but appeared groggy in the locker room.

“He kept battling, he kept his eyes downfield,” Reid said. “There were some positives.”
Vick threw a 2-yard touchdown pass to Riley Cooper in the first quarter.
