This video is incredible
Clint Malarchuk mere moments after having his jugular vein severed during a game on March 22, 1989. The wound was closed after 300 stitches and he avoided becoming the third NHL player to die from an in-game injury
One of the trainers had been a medic in Vietnam, and was able to hold his jugular closed until he could receive treatment.
Easily the most intense moment in sports history.
