"I really can't say if I should have or shouldn't have played," said Vick, who had 21 days between games and an original prognosis of 10 to 14 days out of action.
Vick was a full participant in practice throughout the week. Coach Chip Kelly said he did not see any ill effects and that Vick had told him he felt "great," but Kelly added that he was "concerned all week long" about the situation.
Rookie Matt Barkley relieved Vick, but he couldn't help the Eagles find the end zone in more than two quarters of duty. Their lone touchdown came on special teams, and the Eagles attack spoiled another solid effort from a defense that held the Giants to five field goals.
The Eagles' current situation appears dire. Their top two quarterbacks are injured. The offense has not scored a touchdown in two games. They are 3-5, and have lost 10 consecutive games at Lincoln Financial Field. Kelly, the innovative offseason hire, has seen his system stagnate and his judgment questioned.
"We've had some instability at the quarterback position," Kelly said. "I think we've also got to step up. And it starts with me. I'm the play-caller, I'm the guy calling plays. In the last two weeks, I haven't done a very good job of it."
The Eagles recorded only 201 total yards. Barkley finished 17 of 26 for 158 yards, with one interception and a fumble. Vick went 6 of 9 for 31 yards and an interception. LeSean McCoy, whom the team vowed to reignite, rushed for 48 yards. DeSean Jackson was the top receiver, but he was limited to 63 yards.
The problems on offense began during the first drive. With his first two reads covered, Vick threw an interception behind Brent Celek. Vick was sacked on the next drive and settled for a three-and-out. Vick's injury occurred on the third drive, which also concluded with a punt.
Vick conferred with the team physician on the sideline and also spoke to Kelly. He played him for one more drive, but both the coach and quarterback agreed that Vick could not finish the game.
"At some point, we all would have realized that I wasn't 100 percent," Vick said.
Barkley entered the game with 2 minutes, 24 seconds remaining in the second quarter and the Eagles trailing, 9-0. He connected on six of his first seven passes to bring the ball to the Giants' 2-yard line. During a timeout, Kelly called a play he said the Eagles practice each week in which the quarterback rolls out and checks two receivers. If neither is open, he is to throw the ball away.
Barkley didn't throw it away. He continued rolling out before Giants cornerback Terrell Thomas chased him down and stripped the ball. The Giants recovered, and a scoring opportunity was thwarted.
"I don't know if I was thinking about last week, trying to do too much of forcing it in there, so I was holding onto it, about to throw it away, and they made a good play on it," Barkley said.
The second half didn't go any better. The Giants added two more field goals, and the Eagles offense seldom threatened. When it did, Kelly made curious decisions. With the Eagles trailing, 9-0, Kelly kept his offense on the field on a fourth and 10 instead of attempting a 49-yard field goal.
Kelly chose to punt on fourth and 4 from the Giants' 47-yard line with a 15-0 deficit and 10:21 remaining. There was little the Eagles could do to score points.
The Eagles finally scored late in the fourth quarter when a snap by the Giants' Zak DeOssie sailed over punter Steve Weatherford's head and was recovered by Najee Goode for a touchdown.
After the score, Kelly elected for an onside kick. There was 4:11 remaining and the Eagles had one timeout.
The Eagles could not recover the kick. The Giants moved the chains, and by the time the Eagles reclaimed possession 84 yards from the end zone with 27 seconds remaining, the final score seemed a formality.
Barkley threw an interception, and the fifth loss of the season was sealed. For the second consecutive week, the fourth-round pick could not lead a comeback.
"It is definitely different than starting from scratch . . . but I do not want to make that excuse for how we performed on offense," Barkley said.
The Eagles might need to plan for Barkley to start next week's game in Oakland against the Raiders. Vick's status is unknown, and Nick Foles has not been cleared to return to practice because of a concussion.
Kelly repeatedly mentioned instability at quarterback as the issue for the offense, but the team's issues go beyond that. Kelly's inaugural season has sputtered, and the coach must figure out how to avoid a complete slide.
"If you have instability at the quarterback spot," Kelly said, "we have to figure things out as a coaching staff to make sure we score enough points the way our defense is going right now."
