With 17 minutes remaining in the 1956 FA Cup Final, Manchester City goalkeeper Bert Trautmann injured his neck in a collision and was knocked unconscious. An X-ray three days later revealed his neck was broken. In a time without substitutions, Trautmann decided to stay in the game rather that leave his team outnumbered. He proceeded to make two more saves, including one that knocked him out a second time, securing the 3-1 victory.
Obviously in today's game, this would never happen due to the allowance for substitutions and new rules governing treatment of concussions. Nonetheless, it is insane that Trautmann survived those last 17 minutes.
