Answer: officials at both schools complained about the emphasis on the games over academics
Princeton hosted and won the second game on November 13, so the first season of college football resulted in a tie. Because each game was played under the different rules of the home team (the Princeton rules gave a "free kick" to players that caught the ball), some people believe that the third game was canceled due to a disagreement over the rules, but the majority believe that school officials canceled the game over concerns about the students focusing on the games over their studies.
In 1933, Parke H. Davis, a college football historian, retroactively named both Rutgers and Princeton "college football national champion" for 1869.
