KANSAS CITY, Mo. (AP) The Kansas City Chiefs will have 10 days to stew over Mike Williams' touchdown catch, Philip Rivers' wave as he trotted off the field and the golden opportunity they let slip away Thursday night.

They had led the Los Angeles Chargers nearly wire-to-wire, taking an early 14-0 lead and looking every bit the dominant team in the AFC West. And they still led into the fourth quarter, victory seemingly certain along with all the trappings that would come with it -- clinching the division with two games to go, a first-round playoff bye and perhaps homefield advantage throughout with a little bit of help.

Then their defense failed to make a couple of crucial stops. Their offense failed to pick up a first down when it mattered most. The Chargers made every play to escape with a 29-28 victory.
