07:55 AM ET 11.13 | Coming out of a weekend where a number of quarterbacks were knocked from games, the big one may have come to Pittsburgh, too. Two sources indicated that Steelers quarterback Ben Roethlisberger suffered a separated shoulder in Pittsburgh's Monday night's 13-10 overtime win over the Kansas City Chiefs. Roethlisberger was taken to a Pittsburgh hospital for an MRI exam, according to his agent, Ryan Tollner. In addition, one source indicated that the injury is "unusual," although it's unclear if that is good or bad news. "There's a lot to be figured out and we probably won't know anything definitive until the morning, but that's what the [Steelers] team doctor said," a source said. Steelers spokesman Burt Lauten said there is no official word on the injury.
