Coming from someone that is diagnosed with Post concussion syndrome due to hockey and fighting, my noggin is sensitive as shit and even now if I dive for a ball in the outfield or get knocked around playing bball, I'll feel cloudy for a couple days. He suffered a "moderate" concussion after two diagnosed "severe" concussions, I have 5, two severe, 2 moderate and one minor that were confirmed by medical staff.....lord knows I probably have a couple others that I just downed a few beers, lit up a joint to ease the pain back in the day. But at the level he plays at, I just hope for his safety......if a return is possible, I hope he's totally cleared. He did it right the second time taking his time to come back and Boston's medical staff and coaches have been great about not allowing Horton, Savard and Bergy back on the ice until they were 100% cleared.
