Vick hasn’t played since suffering a concussion during a loss to the Cowboys on Nov. 11. He was recently cleared to return.
The Eagles (4-11) went 1-5 with the 23-year-old Foles as the starter.
“I banged it up a little in the first half,” he said. “It didn’t affect my throwing at all.”
An MRI taken on Monday revealed a hairline fracture, Reid said.
“He was in quite a little bit of pain,” Reid said of Foles, who threw for 345 yards. “I know at one point he was having a tough time squeezing the ball when we went into halftime. He’s a tough kid and never said a word about it. . He pushed himself through and did a good job.”
Foles, a third-round pick out of Arizona, completed 60.8 percent of his passes for an Eagles rookie record 1,699 yards, with six touchdowns and five interceptions in seven games following Vick’s injury.
“It’s frustrating because I’m hard on myself and I want to win, but I’m going to keep working hard, and I know my teammates are, too,” Foles said after Sunday’s loss. “We’re going to keep sticking together. It’s been a tough year.”
With Reid’s status as head coach uncertain, it’s impossible to determine whether Foles will get an opportunity with the Eagles next year. But Reid said he was impressed with what he saw over the past two months from Foles.
“I think he’s a winning quarterback or he’s a quarterback that gives your team an opportunity to win,” Reid said. “I think you’re seeing him in a unique situation where he comes in later in the season. You look at the young quarterbacks who’ve had an opportunity to come up through and they’ve had time here to grow.
“It wasn’t really pretty when they first began and it continued to pick up as they got games under their belts. Nick got thrown in when other teams were working to their peaks. He was thrown in in that situation.
“He has enough skill and ability to play.”
