The Packers also have former Wisconsin Badgers quarterback Scott Tolzien, who was promoted today to Green Bay's active roster.
There has been some speculation that Green Bay could reach out to former backup Matt Flynn, who has bounced around the league since leaving the Packers, and was most recently released from the Buffalo Bills. However, according to ESPN's Rob Demovsky, the Packers have concerns about Flynn's arm strength, and will not pursue him.
The last time Rodgers went down with an injury was back in 2010, when he left a week 14 matchup with the Detroit Lions with a concussion.
Back then, Flynn stepped in and played well until Rodgers returned two weeks later. The Packers eventually went on to win the Super Bowl.
