Earl Edwin Morrall (May 17, 1934 – April 25, 2014) was an American football player who was a quarterback in the National Football League (NFL) for twenty-one seasons. Morrall, who also occasionally punted, played 21 seasons in the National Football League as both a starter and reserve. In the latter capacity, he became known as one of the greatest backup quarterbacks in NFL history. During the 1968 Baltimore Colts season, he filled in for an injured Johnny Unitas leading to an NFL championship shutout victory and Super Bowl III, and for the 1972 Miami Dolphins season (both under coach Don Shula) he filled in for an injured Bob Griese leading to Super Bowl VII and the only perfect season in NFL history. Morrall made Pro Bowl appearances following the 1957 and 1968 seasons.
