Outside linebacker Jonathan Abraham has left the Arizona Cardinals and is considering retiring from the game.

The Cardinals confirmed that Abraham had left and announced they had been granted a roster exemption, using it to re-sign linebacker Marcus Benard.

The 36-year-old Abraham sustained a concussion in Monday night's 18-17 season-opening victory over San Diego.

Abraham, in his 16th NFL season, ranks ninth on the NFL's career sacks list with 133½.

He missed nearly all of training camp to, as he later confirmed, undergo rehabilitation treatment for an alcohol problem.
