  • Patrick Mahomes is expected to play for the AFC Championship Game between the Bengals and Chiefs on Sunday -- but he'll be wobbly.
  • How much does that affect betting odds, the spread and the moneyline for this pivotal contest?
  • In a perfect world, what would the Chiefs' line be with Mahomes at 100%? What about if he was out? How injured does the market think Mahomes is?

Chiefs quarterback Patrick Mahomes suffered a high ankle sprain during the divisional round but is expected to play in the AFC Championship Game vs. the Bengals.

This raises the question: How has Mahomes’ ailment — whether he plays or not — affected betting odds for a heavyweight matchup between the Bengals and Chiefs?

The consensus price on the Chiefs spread as of Wednesday afternoon is at roughly +1.5.

But if Mahomes were at 100% health, that fair value line should be closer to Kansas City -2.5 — a four-point swing.

The current market price on the moneyline also bakes into its price the fact that Mahomes won’t be 100%. While the current moneyline hovers at around +100, the fair market price should be -130 with a pre-ankle sprain Mahomes.

If we’re to extrapolate and get granular with the numbers here, that indicates the market thinks Mahomes will be at roughly 70-75% strength relative to a week ago and is pricing accordingly.

The Chiefs are about 57% favorites to win this game with a full-strength Mahomes at Arrowhead Stadium. Those are odds are about -130.

But, the current odds are at -104 at FanDuel. They’re as low as +110 at SuperBook. That implies a win probability of about 48%.

Without their MVP quarterback? The line would balloon to +5.5, with the Bengals being substantial road favorites against the No. 1 seed — one of the highest lines in history for a visitor during the championship round.

As it stands, the Chiefs are +1 (-110) underdogs at FanDuel. The 70-75% Mahomes health assessment the market made with the moneyline translates over for the spread.
