Concussion Protocol (and updates, please)

[No-huddle Joe]

Just a couple questions here.....What "symptoms" are we talking about here? Bad headaches? Being sick to your stomach? Not being a smarta** here, just don't really know what they are looking for in particular. Question #2....did anyone re-watch the game and see when or what exactly happened to him? I don't remember during the game any mention of it until later. I am hoping it was just a mild knee to the head or something that the booth saw and made him come out. I just don't recall any severe blow or anything, at least nothing that they replayed.
