Kero was knocked out cold by Connolly's huge hit

Only 3 minutes had elapsed when Chicago Blackhawks forward Brett Connolly stepped into Kero and delivered a brutal hit, knocking him out. Connolly's hit did not appear to be predatory, but Kero was not looking up the ice, never touched the puck, and could not see Connolly approaching. That, in my opinion, made the strike much worse on Kero, who had seemingly become the victim.
