<P> The National Football League (NFL) on Thanksgiving Day is a traditional series of games played during the Thanksgiving holiday in the United States . It has been a regular occurrence since the league's inception in 1920 . Currently, three NFL games are played every Thanksgiving . The first two are hosted by the Detroit Lions and the Dallas Cowboys; a third game, with no fixed opponents, has been played annually since 2006 . </P> <P> The concept of American football games being played on Thanksgiving Day dates back to 1876, shortly after the game had been invented, as it was a day that most people had off from work . In that year, the college football teams at Yale and Princeton began an annual tradition of playing each other on Thanksgiving Day . The University of Michigan also made it a tradition to play annual Thanksgiving games, holding 19 such games from 1885 to 1905 . The Thanksgiving Day games between Michigan and the Chicago Maroons in the 1890s have been cited as "The Beginning of Thanksgiving Day Football ." In some areas, high - school teams play on Thanksgiving, usually to wrap - up the regular - season . </P> <P> By the time football had become a professional event, playing on Thanksgiving had already become an institution . Records of pro football being played on Thanksgiving date back to as early as the 1890s, with the first pro--am team, the Allegheny Athletic Association of Pittsburgh, Pennsylvania . In 1902, the "National" Football League, a Major League Baseball - backed organization based entirely in Pennsylvania and unrelated to the current NFL, attempted to settle its championship over Thanksgiving weekend; after the game ended in a tie, eventually all three teams in the league claimed to have won the title . Members of the Ohio League, during its early years, usually placed their marquee matchups on Thanksgiving Day . For instance, in 1905 and 1906 the Latrobe Athletic Association and Canton Bulldogs, considered at the time to be two of the best teams in professional football (along with the Massillon Tigers), played on Thanksgiving . A rigging scandal with the Tigers leading up to the 1906 game led to severe drops in attendance for the Bulldogs and ultimately led to their suspension of operations . During the 1910s, the Ohio League stopped holding Thanksgiving games because many of its players coached high school teams and were unavailable . This was not the case in other regional circuits: in 1919, the New York Pro Football League featured a Thanksgiving matchup between the Buffalo Prospects and the Rochester Jeffersons . The game ended in a scoreless tie, leading to a rematch the next Sunday for the league championship . </P>
