Pittsburgh Steelers quarterback Ben Roethlisberger is in the concussion protocol after taking a hit to the head in practice on Tuesday. There aren't really any clear reports as to what happened other than he took a hit to the head.
Roethlisberger clearly was in some discomfort. While it's unclear whether or not Big Ben was hit or fell and hit his head, it appears as if he didn't have a red QB practice jersey on at the time of the injury.
Just a suggestion, but maybe you want your starting quarterback to wear one of those in practice. It is possible Ben missed the feeling of a concussion and did it to himself. He does love contact.
