SAN DIEGO - The San Diego Chargers' three-year playoff drought is over, thanks to another epic, heart-stopping win over the Kansas City Chiefs.

The Chargers have needed help for weeks, and everything fell into place Sunday, with the last piece a 27-24 overtime victory over the Chiefs, who already had clinched the AFC's No. 5 seed. Coach Andy Reid rested 20 of 22 starters.

Nick Novak kicked a 36-yard field goal with 5 minutes, 30 seconds left in overtime. The Chargers, who trailed by 10 points in the fourth quarter, then held the Chiefs on downs to win it after they reached the San Diego 41.

Earlier in the day, the Chargers (9-7) got the help they needed when Miami and Baltimore lost. San Diego has won four straight and five of six heading into a wild-card game next weekend at AFC North champion Cincinnati.

The Chiefs (11-5) go into the playoffs having lost five of seven. They play at AFC South champion Indianapolis, which won, 23-7, in Kansas City last week.

Kansas City kicker Ryan Succop was wide right on a potential game-winning, 41-yard field-goal try with four seconds left in regulation.
