Perhaps this was discussed already, but can anyone be certain that these were concussions that he dealt with? Reason I am asking is because after every concussion he had, he was back on the ice within a week, and playing games shortly after. Same with this one, back on ice 2 days after apparent concussion and is now day to day. I know it is different from person to person, but look at Rick Nash, he is still dealing with concussion symptoms months and months after he got it.
Besides, it wouldnt be 1st time pens player was treated for concussion, and was reported as such, only to be something else (see Sid)
