Panthers released NT Ron Edwards.
The move clears roughly $1.67 million in cap space. It could be seen coming from a mile away for a player who signed a three-year, $8.25 million deal after the lockout. Edwards missed all of 2011 with a torn triceps, and was limited to 11 games last season by a dislocated elbow. Going on 34, Edwards wasn't productive when he took the field. He'll have a rough go of it in free agency.
