Chiefs quarterback Alex Smith will miss Sunday's game against the San Diego Chargers because of a lacerated spleen. Chase Daniel will start in his place.

Team trainer Rick Burkholder said Friday that Smith was likely hurt on a hit during the third quarter of last weekend's loss to the Steelers, but the quarterback didn't have significant symptoms.

If the Chargers beat Kansas City, they make the playoffs. The Chiefs would need to win and have Baltimore and Houston lose to earn a postseason berth.
