Philadelphia Eagles quarterback Michael Vick aggravated his left hamstring injury during a loss to the New York Giants.
Vick first injured the hamstring Oct. 6. He was replaced by Matt Barkley, who turned the ball over twice in a 15-7 loss to New York.
"I felt the same feeling that I had the first time," Vick told reporters, adding that he will undergo a magnetic resonance imaging exam. "I don't think it's as bad, but it did pop again. I've never had a hamstring injury this bad."
Vick was forced into action early with Nick Foles sidelined with a concussion. Vick was intercepted once and also fumbled.
"Once Nick got hurt last week, I just made up my mind that I was going to try to get out there," Vick said. "I was going to try to rehab as hard as I could all week and try to put myself in a position where I could get back behind the center and help our team win. I really can't say if I should have or shouldn't have played.
"I felt good going in. I felt like I did everything that I was supposed to do to reassure myself that I could go out and play. There's just nothing like actually being in the moment and having to move and having to react. I tested it plenty of times, but there's no simulation for guys coming at you, going to hit you."
