@BigRedBuster that might be a little extreme (possibly intentionally so). Though I have not standing to know for sure. Not sure that person does either.
But I definitely think he should be out for several weeks at least. I find it very hard to believe that the hit last week caused the issues we saw. In my completely uneducated opinion, that is a textbook case of Second Impact Syndrome. The first one wasn't seen as very bad so he played but then it didn't take much of a second hit to produce some ugly results.
So he needs plenty of time to recover before being subjected to any other potential impacts.
