In the final seconds of the 1967 NFL Championship Game, the famous Ice Bowl at Green Bay, Pugh was blocked by Packers' guard Jerry Kramer for the game-deciding touchdown. Kramer's block cleared the way for Bart Starr to score on a 1-yard quarterback sneak with 16 seconds remaining, lifting Vince Lombardi's team to a 21–17 victory and an unprecedented third consecutive title game win in weather at Lambeau Field. It was the second consecutive season that Dallas had fallen to the Packers in the championship game; the previous year was a close game in the Cotton Bowl. Always a team player, Pugh carried on through the 1971 season with a case of appendicitis and delayed his surgery until the offseason, by taking shots of penicillin.
