Scott Tolzien replaced starter Seneca Wallace as the Green Bay Packers quarterback after Wallace left Sunday's game against the Philadelphia Eagles with a groin injury.
The injury occurred during Green Bay's first offensive possession.
Wallace started for Aaron Rodgers, who is out with a fractured left collar bone.
The Packers announced that Wallace's return is questionable.
Tolzien was promoted from the practice squad last week.
The Packers were already planning to have Matt Flynn in for a workout on Monday, according to ESPN. Flynn, a former Packer, also played for the Seattle Seahawks, Oakland Raiders and Buffalo Bills in the past year.
