Packers quarterback Seneca Wallace left Sunday's game with the Philadelphia Eagles after the team's first series with a groin injury and his return was questionable.
That left Green Bay with Scott Tolzien at quarterback with Aaron Rodgers already out with a left collarbone injury.
Wallace, like Rodgers in last week's loss to the Bears, left after the first series. He appeared to get hurt after being chased out of the pocket after completing a third-and-14 pass to Brandon Bostick at the Eagles 35.
Tolzien, who played at Wisconsin in college, was just signed off the practice squad this week.
For Philadelphia, linebacker Mychal Kendricks (right knee) left the game in the first quarter. His return was questionable.
