KANSAS CITY, Mo. — Alex Smith threw two touchdown passes for Kansas City, and the game clock finally stopped Johnny Manziel as the Chiefs held on to beat the Cleveland Browns 17-13 on Sunday for their franchise record-tying ninth consecutive victory.

Smith threw for 125 yards while running for 54, helping Kansas City (10-5) clinch a playoff berth when Pittsburgh lost to Baltimore moments after its own game ended.

The Chiefs jumped out to a 17-3 halftime lead, but their offense became listless over the final two quarters, just as Manziel was pumping some life into the Browns (3-12).

The former Heisman Trophy winner led Cleveland to 10 straight points, then took over at his 30 with 1:52 left and no timeouts.

The Browns picked up three first downs, and Manziel hit Darius Jennings on fourth-and-10 from the Chiefs 32. But time expired before Manziel could get another snap off.

SAINTS 38, JAGUARS 27: Drew Brees passed for 412 yards and three touchdowns despite his injured right foot, and New Orleans won at home.

Brees, who tore his plantar fascia ligament during a loss to Detroit last Monday, showed no ill effects of the normally painful injury while completing 25 of 36 passes.

Running back Tim Hightower, who missed the previous three seasons because of a knee injury and subsequent complications, consolidated his recent resurgence with 122 yards and two touchdowns rushing for New Orleans (6-9).

RAMS 23, SEAHAWKS 17: Todd Gurley scored on a 2-yard TD run with 10:34 left, Akeem Ayers returned a fumble 45 yards for a touchdown in the first quarter and St. Louis ended Seattle’s five-game winning streak with a victory in Seattle.

St. Louis swept the season series from the Seahawks (9-6), having won 34-31 in overtime in Week 1.

And the Rams (7-8) caused the same kinds of problems they did in the opener by flustering quarterback Russell Wilson and slowing down a Seattle offense that had not been stopped for the previous five weeks.

COLTS 18, DOLPHINS 12: Third-string quarterback Charlie Whitehurst came off the bench again for Indianapolis, which made a last-minute defensive stand to keep alive its faint playoff hopes, winning in Miami Gardens, Florida.

The Dolphins (5-10) had a first-and-goal at the 5 with 40 seconds left, but after three consecutive incompletions, rookie center Jamil Douglas appeared to snap the ball prematurely, and Tannehill was sacked by three members of the Colts (7-8).

Indy backup quarterback Matt Hasselbeck departed with an injury for the fourth game in a row, and Whitehurst did just enough after entering in the second quarter, completing two scoring drives.

Lions 32, 49ers 17: Matthew Stafford threw for two touchdowns, including one to Calvin Johnson early in the fourth quarter, and Detroit won at home.

The Lions (6-9) have won five of their last seven games, perhaps giving Coach Jim Caldwell a chance to keep his job for a third season.

The 49ers (4-11) have lost three straight and five of six under first-year coach Jim Tomsula.

BILLS 16, COWBOYS 6: Buffalo rookie Mike Gillislee ran 50 yards for a touchdown with 2:25 remaining to secure a win for the Bills (7-8) over Dallas (4-11) in Orchard Park, New York.

Gillislee finished with 93 yards rushing and led a ground attack that combined for 236 yards.

Karlos Williams scored on a 1-yard run as the Bills overcame an injury-depleted offense playing without running back LeSean McCoy.

TEXANS 34, TITANS 6: Brandon Weeden scored his first career rushing touchdown and threw for two more as Houston took a big step toward clinching the AFC South title by winning in Nashville, Tennessee.

Houston (8-7), which wraps up the regular season by hosting Jacksonville, couldn’t clinch outright with Indianapolis beating Miami 18-12.

BEARS 26, BUCCANEERS 21: Ka’Deem Carey caught a touchdown pass from Jay Cutler, and the third-string running back also scored on a 1-yard run to help Chicago end a three-game losing streak with a win in Tampa, Florida.

Carey’s 1-yard scoring reception put the Bears (6-9) ahead for good early in the fourth quarter.

The second-year pro teamed with Matt Forte and Jeremy Langford to spearhead a rushing attack that produced 174 yards and kept Jameis Winston off the field for long stretches.
