Babe Ruth's Concussion
Ruth was in right field on July 5, 1924, for a doubleheader against the Washington Senators at Griffith Stadium, a match that drew the largest crowd ever to see a ball game in the capital city. In the fourth inning of the opener, he crashed into a concrete wall going after a foul ball and was knocked unconscious for about five minutes. Concerned fans peered over the wall as police, players, the Yankees' trainer and even a stadium soda pop vendor (note his basket) gathered around. The Washington Post reported the next day that despite his injuries, Ruth "gamely insisted on sticking in that game and also the second."
