I had forgotten the injury until you brought it up.
From the Hockeyfeed article:
Then Richard Zednik suffered a similar neck injury when he was a member of the Florida Panthers in 2008. Another trigger for Malarchuk.
Looks like hockey might be a dangerous sport, at least occasionally?
That injury to Malarchuk was right at the peak of time I was playing hockey in a men's league, and was fully into watching hockey with friends, sometimes even three or four nights a week and playing two or even three nights a week. (That was around the time I got married, and surprise...my "hockey involvement" really dropped off after that! My wife put up with the smelly gear in the garage for a few years, but then I hurt my knee and couldn't play anymore.
I am thankful that I was too stupid to dwell on what had happened to him as I was playing, because I am not sure if I could have continued to play if I had. As a goalie, you are on the ice a lot, and people are all around you with their sharp skates.
But, it was damned gruesome. (by the way, it was his jugular that was slashed, not his carotid, and that makes sense. If it had been his jugular, he would not have survived.)
He said, though, given the pain caused by the PTSD and by the actual accident, that he would take the cutting of his neck over the pain and torture of the PTSD. Not even a close choice for him. And, he said, since he had experienced both having his neck cut and experiencing the PTSD, he knew of what he spoke. I believe him.
