Steelers linebacker Jarvis Jones, whose head injury was indeed a concussion, has been listed as questionable for Sunday’s showdown with the Ravens.

Per a league source, Jones’ availability will be determined at game time.

It’s currently unclear whether Jones has received final clearance from an independent neurologist to play. Even if clearance has been obtained, any return of symptoms would (or at least should) prompt the Steelers to shut him down for the game.

Jones has appeared in all five regular-season games, with four starts. He has no sacks.
