Summerall spent ten years as a professional football player in the National Football League, primarily as a placekicker. The Detroit Lions drafted Summerall as a fourth-round draft choice in the 1952 NFL Draft. Summerall played the pre-season with the Lions before breaking his arm, which ended the year for him. After that season, he was traded and went on to play for the Chicago Cardinals from 1953 to 1957 and the New York Giants from 1958 to 1961, during which he was a part of The Greatest Game Ever Played. His best professional year statistically was 1959, when Summerall scored 90 points on 30-for-30 (100%) extra-point kicking and 20-for-29 (69%) field goal kicking.
