Last week, the New York Daily News reported the New York Giants have "reached out" to Flynn.
Things have apparently gone a step further.
On Monday, NFL Network reported that Flynn will work out for the Giants on Tuesday along with quarterback Josh Freeman.
Flynn left the Packers after the 2011 season to sign a three-year, $26 million contract with the Seattle Seahawks. But Flynn couldn't beat out then-rookie Russell Wilson and a year later was traded to the Oakland Raiders, where he again failed to win the starting job.
He re-signed with the Packers last fall and played in five games, helping the Packers to a 2-2-1 record in those games while Aaron Rodgers was sidelined because of a broken collarbone.
The Packers have only two quarterbacks on their current roster, Rodgers and Scott Tolzien. Coach Mike McCarthy said last month at the NFL meetings that he wants Flynn to return to compete with Tolzien for the backup job.
In New York, Flynn could be reunited with new Giants offensive coordinator Ben McAdoo, who was the Packers quarterbacks coach last season.
Flynn's agent, Bill Johnson, did not return a message left at his office on Monday.
