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.
