The next installment of the rivalry between the Kansas City Chiefs and the Buffalo Bills will be written when the two meet in the AFC Championship. … and Patrick Mahomes plans to be healthy enough to as usual serve as a difference-maker.

With the Bills handing the Chiefs starters their first loss of the year back in Week 11, there will be a hint of revenge coming from Andy Reid’s team, but there is one key piece of information that needs to be brought forward.

In the playoffs, the Chiefs are 3-0 against Josh Allen and the Bills.

So yes, the Bills have beaten the Chiefs the last four times in the regular season, but Kansas City has won the last three times in the postseason, which sets up a fascinating matchup on Sunday.

“Just two really good football teams going up against each other,” Mahomes said. “They have great players at every level, both sides of the ball, and they’re well coached. So when you play great football teams like that, it usually ends with that split type of deal. We’ve been able to beat them in the playoffs, and they’ve gotten us in the regular season, but if you look at the games, every game’s close, so it just comes down to a play here or there that kind of usually makes an impact on the outcome.”

One key: The health of the important participants … and as it happens, on Wednesday, Mahomes has popped up on the injury report.

It’s that bothersome ankle … though the QB is listed as a full participant.

The Bills are back to the AFC Championship game for the first time since 2020 (when they lost to the Chiefs), while Mahomes and Co. are into their seventh straight AFC title game.

With a shot at history still on the cards, the Chiefs have two more games to navigate to make it a reality.

Rested and at home, Reid’s team has a great chance to advance to yet another Super Bowl, and this latest chapter in the Chiefs/Bills rivalry looms as the best one yet.
