NFL Media Insider Ian Rapoport reported Wednesday the Arizona Cardinals linebacker -- who suffered a concussion during Monday's win over the San Diego Chargers -- has taken leave from the team, per a source close to him. As he considers retirement, Abraham has been placed on the reserve list, giving him five days to make a decision on his playing future.
If Abraham does not return, it counts as a significant setback for a Cardinals defense that doesn't have another established player who can get to the quarterback. Abraham had a team-high 11.5 sacks last season and 133.5 sacks in his 15-year career. That total places him ninth on the NFL's all-time list.
"He indicated to us that he just wanted to take a step back and take some time to consider the time and the effort and constraints it takes to play in the NFL," Keim said. "He's played for quite a long time and he'll reassess that and determine in the next couple of days whether he still wants to play."
