KANSAS CITY, Mo. -- Jamaal Charles ran for 86 yards and a touchdown, Alex Smith also ran for a score and the Kansas City Chiefs beat the banged-up Houston Texans 17-16 on Sunday to remain unbeaten.
The Chiefs (7-0) were forced to punt the ball to Houston with 1:46 left in the game.
But after Case Keenum threw an incompletion on first down, the young quarterback was stripped by linebacker Tamba Hali at his 2. Derrick Johnson recovered the fumble for the Chiefs.
Smith simply kneeled on it from there as time ran out, allowing Kansas City to extend the second-best start in franchise history. The 2003 team began the season 9-0. With the Broncos' loss to the Colts, the Chiefs are the NFL's only remaining undefeated team.
Keenum, making his first NFL start in place of the injured Matt Schaub, threw for 271 yards and a touchdown for the Texans (2-4).
But he didn't get much help from his run game after Arian Foster left in the first quarter with a hamstring injury and did not return (see full recap).
Peyton's rally falls short against Luck, Colts
INDIANAPOLIS -- Andrew Luck threw for three touchdowns and ran for another Sunday night, outplaying predecessor Peyton Manning in a 39-33 victory over the previously unbeaten Denver Broncos.
The victory ended the Broncos' 17-game regular-season winning streak in the first game Manning played against his former team since being released in March 2012.
Manning finished 29 of 49 for 386 yards with three TDs and one interception. He was sacked four times and tried desperately to rally the Broncos (6-1) late.
But the Colts (5-2) took advantage of his and Denver's uncharacteristic mistakes.
Luck converted an early fumble into a TD pass. Indy got nine points out of a second-quarter strip sack, and Luck scored on a 10-yard run in the third quarter, a drive helped by a series of defensive penalties. When the Broncos finally had a chance to tie it, Manning was intercepted.
Indianapolis has not lost consecutive games under Luck (see full recap).
Geno, Jets upset Patriots
EAST RUTHERFORD, N.J. -- Nick Folk kicked a 42-yard field goal with 5:07 left in overtime to lift the New York Jets to a 30-27 victory over the New England Patriots on Sunday.
Folk got a second chance after he missed a 56-yarder moments earlier. But Chris Jones was called for unsportsmanlike conduct for pushing a teammate forward to try to block the kick, a new NFL rule.
New York, given new life, ran the ball three times to set up Folk's winner.
Geno Smith threw a touchdown pass and ran for another score as the Jets (4-3) topped Tom Brady and the Patriots (5-2). New England tied it at 27 with 16 seconds left in regulation on Stephen Gostkowski's 44-yard field goal.
New England had defeated New York in six straight regular-season meetings, and saw its 12-game winning streak against the AFC East end (see full recap).
Dalton goes off; Nugent kicks Bengals over Lions
DETROIT -- Mike Nugent's 54-yard field goal as time expired lifted the Cincinnati Bengals to a 27-24 win over the Detroit Lions on Sunday.
The AFC North-leading Bengals (5-2) won a game for the second straight week by the same score thanks to Nugent's right foot. He made an overtime kick to give Cincinnati a win after it blew a 14-point, fourth-quarter lead at Buffalo
The Lions (4-3) looked like they did enough to send the game to OT, but rookie Sam Martin shanked a punt just 28 yards to midfield in the final minute.
Andy Dalton, who threw three touchdown passes, took advantage with two short passes to set up the game-winning field goal.
Detroit's Matthew Stafford connected with Calvin Johnson on two of his three TD passes (see full recap).
Steelers outlast Ravens in field-goal battle
PITTSBURGH -- Shaun Suisham drilled a 42-yard field goal with no time remaining to lift the Pittsburgh Steelers to a 19-16 victory over the Baltimore Ravens on Sunday.
Suisham's fourth field goal of the day pushed the Steelers (2-4) to their second straight win.
Ben Roethlisberger completed 17 of 23 passes for 160 yards and a touchdown. He hit Antonio Brown for a pair of big gains on Pittsburgh's final drive, putting Suisham well within range to win it. Running back Le'Veon Bell ran for a season-high 93 yards on 19 carries.
Joe Flacco passed for 215 yards and a touchdown but couldn't stop the defending Super Bowl champions from losing for the third time in their last four games (see full recap).
