1966 American Football League season

The 1966 American Football League season was the seventh regular season of the American Football League. The league began its merger process with the National Football League (NFL) in June, which took effect fully in 1970. The season also saw the debut of the expansion Miami Dolphins, the AFL's ninth team (an odd number), requiring an idle team each week. A sixth official, the Line Judge, was added to the officiating crew; the NFL added the Line Judge the previous season.
