Looks like he will be okay. Probably out for the season, but with something like that, that's best case scenario.
The Bengals/Steelers games over the past 4-5 years have become more dangerous than competitive. Both teams are naturally hard hitting to begin with, but it's gotten to the point where they are both targeting for each others heads and it's scary to watch. At the end of the day, no matter how much you hate another team as a fan, those guys still have families and a life outside of football. You want a hard hitting but clean game and this game has become anything but that.
