Box Score == Aftermath ==

The game was the first playoff win in the Dolphins' young franchise history. The Dolphins advanced to the AFC Championship Game, where they blanked the Baltimore Colts 21–0 to advance to Super Bowl VI, losing 24–3 to the Dallas Cowboys. The Dolphins would go on make the following two Super Bowls, winning both, including a perfect season the following year. The Chiefs would not reach the playoffs again until 1986 and would not reach the Divisional Round again until 1991. Due to the game being played on Christmas, the NFL received numerous complaints, due to how it caused affected Christmas dinners around the nation, as well as playing the game on a traditional religious and family holiday, with a Kansas state legislator proposing a bill to ban the scheduling of future games on December 25. Due to these complaints, the NFL would deliberately set the schedule in later seasons to avoid having any games on Christmas. When Christmas fell on a Sunday in , , and , the NFL scheduled the divisional round games set for that weekend on December 24 and 26. When Christmas fell on a Saturday in and , the NFL started the season a week earlier to play conference championship games on December 26 in 1976 and started the season a week later with the regular season set to end with every team playing on December 26 (though a strike would delay the season ending by a week) in 1982. It would not be until a Monday Night Football game in between Cincinnati and Minnesota that another NFL game would be played on Christmas. Following that, through 2020, whenever Christmas fell on a Saturday, Sunday, or Monday (as well as a Friday in and ), the NFL scheduled at least one game. Starting in , the NFL began regularly scheduling multiple games on Christmas, regardless of day of the week. Following the game, an estimated 20,000 Dolphins fans waited for the team to return at Miami International Airport, a surprise to the team, who usually only had few people wait for them. Yepremian, whose kick won the Dolphins the game, was presented with two bottles of champagne by the president of the charter's airline. He was escorted to the police station in the basement for a celebration. Following his return home, the whole block was decorated and neighborhood kids (one of which was future MLB pitcher Marty Bystrom) knocked on his door. Dolphins coach Don Shula and his son David found their car unable to start and had to hitchhike back to their home with the help of a Dolphins fan, who they invited in for a drink to thank after being dropped off. == Legacy ==
