SAN DIEGO (AP) — Nick Novak kicked a 36-yard field goal with 5:30 left in overtime and the San Diego Chargers, who trailed by 10 points in the fourth quarter, beat the Kansas Chiefs 27-24 to claim the AFC’s final playoff spot.

The Chargers (9-7) ended a three-year postseason drought. The winning drive was kept alive by a 2-yard gain by Pro Bowl safety Eric Weddle on a fake punt on fourth-and-2 from the Chargers 28. The game ended when Kansas City couldn’t convert on fourth-and-15 from the San Diego 41 with 3:16 left.

With the Chargers on the verge of an embarrassing collapse against a team resting 20 of 22 starters, Philip Rivers threw a 6-yard touchdown pass to Eddie Royal early in the fourth quarter and Novak kicked a 22-yard field goal to tie it.

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

SEATTLE (AP) — Malcolm Smith returned an interception 37 yards for a touchdown, Marshawn Lynch added a 2-yard scoring run and the Seattle Seahawks clinched the NFC West title and home-field advantage throughout the playoffs with a 27-9 win over the St. Louis Rams on Sunday.

Seattle (13-3) matched the franchise record for wins in a season and finally wrapped up the No. 1 seed after failing in two previous attempts, including last week’s loss to Arizona that snapped a 14-game home winning streak.

Smith’s interception was the start of a dominant performance by the Seahawks defense that held St. Louis under 100 yards of total offense into the fourth quarter.

The defensive effort and a lack of discipline from the Rams (7-9) helped Seattle’s offense do just enough. Russell Wilson threw a 47-yard TD pass to Golden Tate, and Lynch finished with 97 yards rushing.
