In 1954, Lattner was drafted in the first round by the Pittsburgh Steelers, but played with them for only one season before entering the United States Air Force for two years. There, during a football game, he suffered a severe knee injury that prevented him from ever playing professional football again. Lattner's single season in Pittsburgh was a success, as he totaled over 1,000 all purpose yards on offense and special teams. As a result, he was named to the NFL 1954 Pro Bowl as a kick and punt returner.
