In 1919, several players suffered season-ending injuries, and Pitt stumbled to a 6–2–1 record that included another victory over Georgia Tech. The Panthers returned to undefeated status during 1920, albeit with ties against Syracuse and undefeated Penn State. The Penn State game ended in a scoreless tie after Pitt star Tom Davies, who was injured early in the game, returned later to miss a possible game-winning field goal. For the 1921 season, the team's record dipped to 5–3–1, but Pitt made college football history on October 8, 1921. Harold W. Arlin announced the first live radio broadcast of a college football game in the United States from Forbes Field on KDKA radio as the Pitt Panthers defeated West Virginia 21–13 in the annual Backyard Brawl.
