I recall hearing about this happening another time. If my memory is correct, the only reason that guy survived is because the team medic was also an army medic
It's happened a few times that I remember, Zednik in 07 (ish) and most famously with Clint Malarchuk back in the 80s.
Iirc Malarchuk only survived because there was a former army doc literally sitting behind the net, which happened to be where the door was to access the ice.
I know there's a video floating around of this. I have heard that it's quite traumatic to watch. Do not post it here. If it gets posted, it will be taken down.
If you see it posted here, please report it and send me a DM.
