SAN DIEGO — The Kansas City Chiefs had nothing to play for and rested 20 of 22 starters.

They still almost beat San Diego with its season on the line.

Already assured of the AFC’s No. 5 seed, the Chiefs lost 27-24 in overtime Sunday to the division rival Chargers, who claimed the AFC’s final postseason berth.

After the Chiefs blew a 10-point fourth-quarter lead.

Kansas City kicker Ryan Succop, whose family hails from Butler County, was wide right on a potential game-winning, 41-yard field goal try with 4 seconds left in regulation.

“I was proud of the guys for the way they battled,” Chiefs coach Andy Reid said. “Our guys came out and gave everything they could to take it into overtime.”
