The Kansas City Chiefs and the Buffalo Bills go head-to-head in the AFC Conference Championship game on Sunday.

The rivalry between the Buffalo Bills and the Kansas City Chiefs will add a chapter to its story this Sunday in the AFC championship at Arrowhead Stadium. These two teams are very familiar with one another.
