Abraham returned to the Cardinals this past week after he left the team to weigh his future, but it appears he was unable to pass the concussion protocol.
Previous reports mentioned that Abraham has been dealing with memory loss, so it would not be surprising to see him consider retirement in the next few months.
Abraham, 36, is in the final year of his two-year, $4.6 million contract and has a base salary of $2.5 million for the 2014 season.
If this is the end of Abraham’s career, he would have finished with 446 tackles, 133.5 sacks, 47 forced fumbles and an interception. Abraham is also a five-time Pro Bowl selection and a two-time First-Team All-Pro.
