The Chiefs have finally been beaten and the 1972 Dolphins can rest easy.
Josh Allen’s electric 26-yard run in the fourth quarter helped lead the Bills to a 30-21 win, handing the Chiefs their first loss since Christmas Day last year.
The Bills led 23-21 with just over two minutes left in the game when Allen scrambled on fourth-and-2.
The Buffalo quarterback found a hole and busted through it as four Chiefs defenders missed tackles and then Allen trucked his way through a fifth player on his way into the end zone.
The last team to beat Kansas City was the Raiders in a 20-14 defeat at Arrowhead Stadium.
The 1972 Dolphins are the only undefeated team to win the Super Bowl.
