Myhra is known for kicking the game-tying field goal for the Baltimore Colts with seven seconds to go in the fourth quarter of the 1958 NFL Championship Game. His field goal pushed the game into overtime, marking the first occasion in professional football history that any game had moved into an extra period. The game was eventually won by the Colts on a touchdown by Alan Ameche, and has since become referred to as "The Greatest Game Ever Played".
