Arizona Cardinals linebacker John Abraham Tuesday did not pass a concussion protocol and will try again to pass on Wednesday in order to be reinstated for the team's game against division rival San Francisco, according to Fox Sports Alex Marvez.

Cardinals head coach Bruce Arians told media Tuesday Abraham was unsettled by the first reported concussion of his career, and considered walking away from the game.

Abraham only returned to the team Monday and is listed as day-to-day according to Rotoworld.

Arizona signed former Dallas Cowboy OLB Victor Butler Tuesday, but the move is not seen as a replacement for Abraham. The team also released linebacker Marcus Benard as well as punter Drew Butler, leaving an open roster spot Abraham could still fill. 

Abraham is the NFL's active career leader in sacks, with 133.5. He suffered a concussion in Week One in the Cardinals' victory over the San Diego Chargers
