The 36-year-old Abraham is one of the few pass rushing options on the Cardinals The veteran has 133.5 career sacks – ninth all-time.
To compensate for Abraham leaving the team the Cardinals have signed Marcus Benard who played 12 games for the team last season but had been released on Aug. 30 prior to the regular season.
As AZ Central notes, “if Abraham doesn’t return within five days, he will be placed on the reserved/left team list and cannot play this season.”
Abraham suffered his concussion in the third quarter against the Chargers when he banged up against an offensive lineman. He left the field and did not return. The Cardinals are already without Daryl Washington (suspension) and Darnell Dockett (torn knee ligament) for the season.
The veteran Abraham had 11.5 sacks a year ago, the most on the team.
