He made a big play in the 1958 NFL Championship Game when he prevented the New York Giants from gaining a first down by tackling Frank Gifford just a yard before the first down mark. He fractured his ankle on that same play but, as a team captain, insisted on watching the rest of the historic overtime contest from the sideline with his teammates rather than seeking immediate medical attention in the locker room. The injury forced him to miss the Pro Bowl that year and ended his string of nine consecutive Pro Bowl appearances. Marchetti was First-team All-Pro nine times and a Second-team selection once.
