Only difference is that the victim didn't break a neck here.
Recap - Scotty Nichol was taken in the net, got up, dropped his glove and sucker punched Spacek in the jaw.
In my opinion, the only difference was that Spacek didn't break his neck. Infact, Nichol's sucker punch was worse than Bertuzzi's in my opinion.
I searched Youtube but can't find a video.
TSN.ca will have the highlights.
