Tyler Sullivan: The Bills won the regular-season matchup, and Kansas City will win in the playoffs. That's how this rivalry has gone and will continue to go here. Buffalo's weakness on third down will be the tipping point. Chiefs 30, Bills 17 SportsLine's consensus line for the AFC Championship has the Chiefs (-1.5) as narrow favorites.

The Bills will be missing starting safety Taylor Rapp, who is out with a hip injury. Rapp came up with an interception of Lamar Jackson and added a pass breakup in last week’s AFC Divisional Round victory. Rookie Cole Bishop, a second-round pick from Utah, will get the start.
