Gilford R. Duggan was a professional football player in the National Football League and later the All-America Football Conference. He played in the NFL from 1940–1945. He played for the New York Giants, Chicago Cardinals and "Card-Pitt", a team that was the result of a temporary merger between the Cardinals and the Pittsburgh Steelers. The teams' merger was result of the manning shortages experienced league-wide due to World War II. In 1946, Duggan jumped to the rival AAFC, where he played with the Los Angeles Dons in 1946 and the Buffalo Bills in 1947.
