San Diego ? A police officer won’t face criminal charges for shooting and wounding former San Diego Chargers linebacker Steve Foley during a late-night confrontation in September 2006.

San Diego District Attorney Bonnie Dumanis said Friday that Officer Aaron Mansker acted in self-defense.

Mansker was off duty, out of uniform and driving his own car on Sept. 3, 2006, when he tailed Foley to his suburban home on suspicion that the football player was driving drunk.

Foley, who was unarmed, got out of the car to confront Mansker, who responded by shooting the player in the left leg, hip and hand. The injuries ended Foley’s football career.
