John Abraham is a 36-year-old linebacker who plays for the Arizona Cardinals. He suffered a concussion during his team’s September 8 game; though it was Abraham’s first reported career concussion, ESPN’s Adam Shefter reported that he was already having trouble with memory loss. Abraham took a leave of absence from the team and was said to be considering retirement. That’s no longer the case, per Cardinals coach Bruce Arians (i.e. “BA”):
Broncos wide receiver Wes Welker, who suffered his third concussion in the last year in a preseason game, is also expected to return to play.
