Roethlisberger has an old Favre injury

PITTSBURGH -- The sternoclavicular sprain that Ben Roethlisberger is dealing with is considered uncommon. But this is the same injury that forced Brett Favre to end his ironman streak of 297 consecutive games played. Favre returned after missing one game before sustaining a season-ending concussion.

The sternoclavicular joint is the connection of the sternum (breastbone) to the clavicle. According to Harvard Health Publications, SC joint sprains occur most often "when a driver's chest strikes the steering wheel during an auto accident, or when a person is crushed by an object."

The odds are probably against Roethlisberger playing Sunday night with this shoulder sprain, although Roethlisberger can never be completely ruled out because of his track record of playing with injuries. It will ultimately depend on his pain tolerance and getting his throwing motion back.
