FLOWERY BRANCH, Ga. -- The Atlanta Falcons placed Keion Carpenter on injured reserve Thursday, meaning the backup free safety will miss the entire season.
Carpenter, in his third year with the Falcons, tore his anterior cruciate ligament during a workout last week. He had knee surgery Tuesday performed by Dr. James Andrews.
Carpenter struggled last season along with the rest of Atlanta's pass defense. The Falcons allowed a franchise-record 6,108 total yards and ranked last in the NFL against the pass.
After losing his starting job midway through last year, Carpenter played some in nickel coverage - but he never regained his 2002 form following spinal fusion surgery. He had four interceptions and set career highs with 74 tackles and nine passes broken up two years ago.
The Buffalo Bills signed Carpenter as an undrafted free agent out of Virginia Tech in 1999.
