On June 9, 1962, Geiger crashed directly into the center field wall at Fenway Park attempting to catch a Tito Francona drive as the Red Sox lost to his old team Cleveland in 13 innings. He ventured back on the dirt track and looked as if he were going to come up with the ball. He made a sudden leap for it but struck the wall, and the ball caromed back onto the field. He landed on his feet, clapped his head with his arm, sank slowly to his knees and fell flat on the ground. He was removed on a stretcher and taken to a hospital.
