A week from this Sunday, the Kansas City Chiefs will play the San Francisco 49ers for all the marbles: the 2019 NFL championship in Super Bowl LIV.
The last time the Chiefs played in this game was after the 1969 season, when the Chiefs defeated the Minnesota Vikings 23-7 during Super Bowl IV in New Orleans’ Tulane Stadium. It was the final Super Bowl between and AFL and NFL teams; as set out in an agreement between the leagues before the 1966 season, the American Football League was absorbed into the NFL immediately afterward.
