There is no official word on the injury suffered by Pittsburgh Steelers QB Ben Roethlisberger but I can tell you it does not look good by looking at the replay. Watch as St. Louis Rams safety Mark Barron makes the tackle on Roethlisberger and then watch as his knee bends in a way that knees aren't supposed to bend.
Here was the end-zone angle on Roethlisberger I mentioned https://t.co/b4orypXqNo

Former NFL team doctor David Chao writes on twitter that, based on looking at the replays, it appears that Roethlisberger has an MCL injury but that's not official.
