In the early 20th century, football began to catch on in the general population of the United States and was the subject of intense competition and rivalry, albeit of a localized nature. Although payments to players were considered unsporting and dishonorable at the time, a Pittsburgh area club, the Allegheny Athletic Association, of the unofficial western Pennsylvania football circuit, surreptitiously hired former Yale All-American guard Pudge Heffelfinger. On November 12, 1892, Heffelfinger became the first known professional football player. He was paid $500 to play in a game against the Pittsburgh Athletic Club. Heffelfinger picked up a Pittsburgh fumble and ran 35 yards for a touchdown, winning the game 4–0 for Allegheny. Although observers held suspicions, the payment remained a secret for years.
