1988: U.S. Olympic diver Greg Louganis suffers a concussion after hitting his head on the springboard during the preliminary rounds at the Summer Olympics in Seoul, South Korea. Louganis would complete the preliminaries despite the injury, earning the highest single score of the qualifying for his next dive, and eventually repeat his gold-medal-winning performance from 1984. He would also repeat as gold medal winner in the 10-meter platform diving event in Seoul.
