Jerry, who turns 30 on Aug. 23, was the 24th overall pick in 2009 out of Mississippi. He battled injuries throughout his five seasons with the Falcons.
The team signed him to a one-year contract this offseason at a low-risk price of $890,000. His base salary would have been $730,000.
He's the second player this year to abruptly retire, as running back Jason Snelling left the team in March.
