"[Roethlisberger] has a shoulder sprain [that] can be classified as an SC sprain,''
Tomlin said. "That's all the information that I have for you at this time. He's being evaluated. Obviously, this injury puts his participation in the questionable category this week.''
An SC joint sprain, basically, is a tear in the joint that connects the sternum to the clavicle. It controls the movement in that area, so range of motion will be an issue for Roethlisberger. Surgery generally isn't needed for this injury, which would be treated with rest and pain meds. Even a less serious form of an SC joint sprain could take at least three weeks to heal.

Apparently it's the same injury that stopped Favre's consecutive games streak. The sports medicine doc on 105.7 this morning said he'll be shocked if Ben plays with that injury.
