The latest chapter in the Buffalo Bills-Kansas City Chiefs rivalry will be written on Sunday afternoon.
The Chiefs are appearing in their seventh straight AFC Championship Game and are in search of their fifth Super Bowl appearance in six years.
Buffalo has come close to beating Kansas City in the postseason, but the Chiefs own a 3-0 record against the Bills in the Josh Allen and Patrick Mahomes era.
The last two postseason battles have been decided by a total of nine points. One game went into overtime and the other was decided by a missed game-tying field goal.
