PHILADELPHIA -- Eagles starting free safety Marlin Jackson suffered a ruptured right Achilles tendon in practice Tuesday and will miss the rest of the season.
Jackson, who has a history of leg injuries, had to be taken off the field in a cart.
Jackson, who left the Indianapolis Colts to sign with the Eagles in March, suffered season-ending knee injuries the past two seasons and had surgery on both knees.
He missed the second half of 2008 with a torn ACL in his right knee and tore the ACL in his left knee in 2009.
