During the 1988 Seoul Summer Olympics diving preliminaries, the American diver Greg Louganis, considered by many the greatest of all time, suffered a head concussion when doing a reverse 2 1/2 spike, as the back of his head hit the spring board. However, even with the injury he suffered, and pressured by the fact that he was HIV-positive at the time, he went on to finish the preliminaries and qualified. During the finals and to everyone’s amazement, he repeated the same dive, earning him the gold medal.
Here’s a video remembering those 1988 Olympic moments at Seoul.
