The Kansas City Chiefs will host an AFC Championship Game for a third straight season Sunday as they look to keep their chances of repeating as Super Bowl champions alive against the Buffalo Bills, who are 3-point underdogs despite entering on an NFL-high eight-game winning streak and taking those by an average margin of 17 points per game.

Kansas City will join the Philadelphia Eagles from 2002-04 as the only teams to host three conference championship games in a row. The common link between the franchises? Andy Reid coached those Eagles and of course now coaches the Chiefs.

No question the biggest story that looms over this game is the status of Chiefs superstar quarterback Patrick Mahomes. He left last Sunday’s 22-17 win over Cleveland with a concussion in the third quarter and didn’t return. Mahomes had led Kansas City to a 19-3 halftime lead, but without him the Chiefs nearly blew it – although backup QB Chad Henne delivered on a late fourth-down conversion to clinch the victory.
