The Baltimore Colts season was the 14th season for the team in the National Football League. The Baltimore Colts finished the National Football League's 1966 season with a record of 9 wins and 5 losses and finished second in the Western Conference.
Quarterback Zeke Bratkowski, in relief of Bart Starr, who suffered a muscle spasm in the first half, directed an 80-yard drive in the fourth quarter that resulted in a go-ahead touchdown run by Elijah Pitts for the Packers. John Unitas then led the Colts to the Green Bay 15, but there lost a fumble which came to be known as the 'Million Dollar Fumble', to secure the Packers' win that clinched the Western Conference title for Green Bay.
