Nick Foles, a third-round draft selection, will make his first career start Sunday. Foles earned positive reviews from coach Andy Reid after replacing Vick in last Sunday's game against the Dallas Cowboys.
A source indicated on Monday to ESPN that Foles was in line to start for Vick, who suffered what coach Andy Reid called a "pretty significant concussion." Reid also has emphasized that Vick is still Philadelphia's starter when healthy, according to a source.
Vick, 32, has struggled this season with 11 touchdowns and nine interceptions. After a loss two weeks ago to the Atlanta Falcons, Reid refused to endorse Vick as the starter, needing a couple of days before releasing a statement that there would be no change at quarterback.
Foles was 22-of-32 for 219 yards with a touchdown and an interception against the Cowboys but could not help the Eagles (3-6) avoid their fifth straight loss, a first in Reid's 14 seasons in Philadelphia.
The loss to the rival Cowboys was another black mark on the season, and time is running out to save Reid's job. Eagles owner Jeffrey Lurie put Reid on notice following an 8-8 season that he had to win big to earn a 15th season.
