Sullivan should/could be back by MSU. Don't know the exact injury but sounds like an MCL sprain. (I think they feared it was a tear but came back ok). Mccoy, is more a question mark. It sounds like it is similar to what ailed him for the spring game. (head/neck area). Like, it's possible there could be something really bad, but they can't tell and don't think so. But at the same time don't want to risk it. I'm not really sure and I don't think they are either. Good friend is a high school coach with a former player or two on the team and he's good friends with their parents as well. That's all he had been told, or at least all he told me.
