Frank "Gunner" Gatski (March 18, 1921 – November 22, 2005) was an American football center who played for the Cleveland Browns of the All-America Football Conference (AAFC) and the National Football League (NFL) in the 1940s and 1950s. Gatski was one of the most heralded centers of his era. Known for his strength and consistency, he helped protect quarterback Otto Graham and open up running lanes for fullback Marion Motley as the Browns won seven league championships between 1946 and 1955. Gatski won an eighth championship after he was traded to the Detroit Lions in 1957, his final season.
