Kansas City Chiefs beat Houston Texans to close on top seed

The Kansas City Chiefs closed in on the top seed in the AFC with a 27-19 victory over Houston Texans.

Patrick Mahomes, who overcame an ankle problem to start the game, rushed for one touchdown and threw another to Xavier Worthy as the Chiefs improved their record to 14-1 in their bid to win an unprecedented third successive Super Bowl.

Kansas City will clinch the top seed and a bye to the second round of the play-offs if the Buffalo Bills lose on Sunday or if the Chiefs beat the Pittsburgh Steelers on Christmas Day.
