I watched the video a hundred times. Crosby fell into Niskanen who thrust his hands forward to avoid being a victim of the collision. ALL of my hockey playing friends, coaches, trainers, were horrified to see Crosby hurt but NONE said it was a deliberate intent to injure.   ALL said the game misconduct was wrong and ALL agreed with the player safety department that no further punishment should be allotted. We are talking 8 different opinions here from knowledgeable hockey people. 

I wish the best to Sidney, a Canadian sporting hero,  and hope he returns so we can all continue to be  thrilled by his amazing competitive fight and talent.
