The Cleveland Browns defeat the San Francisco 49ers 21-7 to win the AAFC Championship at Municipal Stadium. It is the final game played in the All-American Football Conference. The league, born in 1946, was the first to reintegrate when the Browns signed Marion Motley and Bill Willis. The Browns would dominate the AAFC, winning the championship all four seasons as they joined the NFL along with the 49ers and Baltimore Colts.
