07:44 AM ET 11.13 | Pittsburgh Steelers quarterback Ben Roethlisberger has a reputation for being one of the toughest quarterbacks in the league, so when he was taken to the hospital and never returned to the Monday Night Football game against the Kansas City Chiefs, there was a reason for concern. Roethlisberger reportedly has a right shoulder separation, and it doesn't look good. He was taken to the hospital for a MRI. Per Jason Cole of Yahoo! Sports, the shoulder separation that Roethlisberger suffered was "unusual." "There's a lot to be figured out and we probably won't know anything definitive until the morning, but that's what the team doctor said," a NFL source said. The Steelers are concerned that Roethlisberger will miss a few weeks, which includes two games against division rival Baltimore Ravens.
