Andy Reid said quarterback Michael Vick injured his chest and will have an MRI in the morning to determine the severity.
Reid said he "goofed" on the play at the end of the first half that led to the Eagles taking a delay of game penalty.
He said the team had a play called for inches and that when they got to the play it was more like a yard.
"That's my fault," Reid said. "I'm trying to explain the thought process on it and that's where I'm going to end it. We had the play called for inches and inches weren't inches when that thing were started … The position of the ball wasn't where we thought. From where it was originally was and where it ended up being were two different spots. That's my responsibility. I'm not here to complain about the officials. I'm not here to complain about anybody else. I goofed."
Replays showed Kevin Kolb walking on the field with the play clock at 11 seconds remaining.
"I wasn't surprised that the clock was moving," Reid said. "I was surprised with how quick it was moving with when it was started with the spot."
Reid again said it was a tale of two halves.
"It was two games," he said. "The first half we didn't play very well, the second half we came out and did some things … They did a better job than we did."
