The New York Giants of the NFL played their home games at Yankee Stadium from 1956 to 1973. On December 28, 1958, Yankee Stadium hosted the 1958 NFL championship game, frequently called "The Greatest Game Ever Played". The Baltimore Colts tied the Giants, 17–17, on a field goal with seven seconds left. Led by quarterback Johnny Unitas, the Colts won in overtime, 23–17. The game's dramatic ending is often cited as elevating professional football to one of the United States' major sports. The game was one of three NFL championships games that were played at Yankee Stadium; the 1956 and 1962 championship games were also played there. In addition to the NFL championship games, one of the most notable plays in NFL history occurred at Yankee Stadium on November 20, 1960. In a game that day, the Philadelphia Eagles' Chuck Bednarik forcefully tackled the Giants' Frank Gifford in the last minute of a close game, forcing a fumble recovered by the Eagles that clinched the victory for Philadelphia and ultimately helped the Eagles dethrone the two-time defending champion Giants as NFL Eastern Conference champions. The hit left Gifford with a concussion and forced his temporary retirement from football for the remainder of the 1960 season and all of the 1961 season.
