The Broncos, Falcons, Ravens, Texans and Patriots took big steps toward making the postseason with victories this week. Denver in the AFC West and Atlanta in the NFC South both have four-game leads after tight road wins Sunday, while Baltimore went to overtime to secure a three-game margin in the AFC North.
Houston and New England did their work on Thanksgiving Day to grab three-game cushions in the AFC South and East, respectively. San Francisco's victory and a loss by Seattle pushed the 49ers' edge to 2 1/2 games in the NFC West.
Denver (8-3) had it much tougher than expected at Kansas City (1-10), but rallied for its sixth straight win as Peyton Manning threw for 285 yards and two touchdowns.
"It's a division opponent; you have to win," Broncos cornerback Champ Bailey said. "You have got to win those games. It is what is going to prepare you for the playoffs."
Manning hit tight end Jacob Tamme late in the first half and wide receiver Demaryius Thomas in the third quarter for scores, and that was more than enough to overcome three field goals by the Chiefs' Ryan Succop as Kansas City lost its eighth straight. Knowshon Moreno added 85 yards rushing in place of Willis McGahee, who went on injured reserve this week with a knee injury.
Jamaal Charles ran for 107 yards for the Chiefs.
The victory, combined with San Diego's 16-13 home loss to Baltimore, put the Broncos in position to win the division next week.
"We have to keep going," Thomas said. "Our goal is to keep winning and get to the big game."
Atlanta (10-1) edged Tampa Bay 24-23 as Matt Ryan threw for 353 yards and overcame two big turnovers by leading another late touchdown drive.
Connor Barth missed a 56-yard goal for Tampa Bay (6-5) in the closing minutes, and the Bucs' four-game winning streak ended.
"Ten-and-1 is great, but I'll tell you what I've said since the beginning of the season: We're just jockeying for position," tight end Tony Gonzalez said. "We just want to put ourselves in the best position, playing the best football. Right around this time is when you want to start jelling as a team and take it on into the playoffs because that's the most important thing."
Elsewhere Sunday, it was San Francisco 31, New Orleans 21; the Giants 38, Green Bay 10; Chicago 28, Minnesota 10; Indianapolis 20, Buffalo 13; Cincinnati 34, Oakland 10; Cleveland 20, Pittsburgh 14; Miami 24, Seattle 21; St. Louis 31, Arizona 17; and Jacksonville 24, Tennessee 19.
On Thursday, Houston won at Detroit 34-31 in overtime; New England routed the New York Jets 49-19; and Washington beat Dallas 38-31.
Monday night, it is Carolina (2-8) at Philadelphia (3-7).
RAVENS 16, CHARGERS 13 OT
At San Diego, the Ravens pulled off a fourth-and-29 conversion to stay alive, then Justin Tucker kicked a 38-yard field with 1:07 left in overtime to complete a stunning comeback.
San Diego (4-7) led 13-3 on Nick Novak's 30-yard field goal and seemed headed for its first win against a team with a winning record this season. But Ray Rice caught a short pass from Joe Flacco and weaved through the defense to the San Diego 33 with 1:37 to play. After a review, the ball was moved back to the 34 and the refs measured. The new spot gave the Ravens a first down by the length of the ball.
Six plays later, Tucker kicked a 38-yard field goal to tie the game as regulation expired.
The Ravens (9-2) won their fourth straight and for the eighth time in nine games.
49ERS 31, SAINTS 21
At New Orleans, the San Francisco defense stymied Drew Brees and ended the Saints' three-game winning streak. Ahmad Brooks and Donte Whitner each returned interceptions for touchdowns and the 49ers (8-2-1) sacked Brees five times.
Colin Kaepernick ran for one score that he made look easy and threw for a touchdown in another performance that validated coach Jim Harbaugh's decision to start him ahead of Alex Smith.
Brees finished with 267 yards and three TDs for New Orleans (5-6).
GIANTS 38, PACKERS 10
At East Rutherford, N.J., Eli Manning threw for three touchdowns, giving him 200 for his career, a team record, and New York sacked Aaron Rodgers five times.
Coming off their bye, the Giants (7-4) put to rest concerns about a dormant offense and a tired arm for Manning. He connected with rookie Rueben Randle, Victor Cruz and Hakeem Nicks for scores, and Ahmad Bradshaw had a combined 119 yards, including a 59-yard sprint on a screen pass to begin the onslaught.
Mathias Kiwanuka had two of the sacks as Rodgers never got comfortable. Green Bay (7-4) had its five-game winning streak snapped.
FALCONS 24, BUCCANEERS 23
At Tampa, Fla., Matt Ryan threw for 353 yards and overcame two big turnovers by leading another late touchdown drive to end Tampa Bay's four-game winning streak.
Michael Turner's 1-yard TD run put Atlanta ahead for good with 7:55 left. Connor Barth missed a 56-yard goal for Tampa Bay (6-5) in the closing minutes, and Josh Freeman's desperation pass fell incomplete in the end zone with no time remaining.
The win enabled the Falcons (10-1) to keep pace with Houston for the NFL's best record.
BEARS 28, VIKINGS 10
At Chicago, Jay Cutler threw for 188 yards and a touchdown after missing a game because of a concussion as Chicago (8-3) ended a two-game losing streak.
The Bears grabbed a 25-3 halftime lead thanks to Cutler's pinpoint passing. The defense held Adrian Peterson in check early on, although he finished with 108 yards rushing for Minnesota (6-5).
The win could prove costly. The Bears lost wide receiver Devin Hester (concussion), running back Matt Forte (ankle), cornerback Charles Tillman (ankle) and both starting guards to injuries.
BRONCOS 17, CHIEFS 9
At Kansas City, Mo., Peyton Manning threw for 285 yards and two touchdowns, and Denver (8-3) rallied for its sixth straight win.
Manning hit tight end Jacob Tamme late in the first half and wide receiver Demaryius Thomas in the third quarter, and that was more than enough to overcome three field goals by the Chiefs' Ryan Succop as Kansas City lost its eighth straight game.
Jamaal Charles ran for 107 yards for the Chiefs (1-10), who haven't scored a touchdown since the first quarter against Pittsburgh on Nov. 12, a span of more than 11 quarters and 173 minutes of game time.
COLTS 20, BILLS 13
At Indianapolis, T.Y. Hilton scored on a 75-yard punt return and caught an 8-yard TD pass from Andrew Luck. He is the first player in franchise history to score by punt return and pass reception in the same game.
Luck was 20 of 37 for 240 yards with a TD and an interception as Indy improved to 7-4.
Buffalo (4-7) ended its red-zone drought with 11:30 left with a 1-yard TD pass from Ryan Fitzpatrick to Lee Smith. But the Bills moved closer to extending their string of non-playoff seasons to 13.
BENGALS 34, RAIDERS 10
At Cincinnati, Andy Dalton threw three touchdown passes in outdueling Cincinnati's former quarterback, Carson Palmer. BenJarvus Green-Ellis ran for 129 yards and a touchdown against the NFL's most generous defense. He had runs of 48 and 39 yards—the longest of his career—to set up scores for the Bengals (6-5).
Palmer had a tough time all-around in his return to Cincinnati, going 19 of 34 for 146 yards with four sacks and an interception.
Oakland (3-8) lost its fourth in a row.
A brawl in the fourth quarter resulted in Oakland's Tommy Kelly and Lamarr Houston and Cincinnati's Andrew Whitworth getting ejected.
BROWNS 20, STEELERS 14
At Cleveland, the Steelers (6-5) committed eight turnovers and third-string quarterback Charlie Batch struggled as the Browns (3-8) beat Pittsburgh for just the second time in 18 games.
Chris Rainey's fumble with 2:25 left was recovered by Cleveland's Phil Taylor to clinch it.
Batch, starting for Pittsburgh because of injuries to Ben Roethlisberger and Byron Leftwich, was picked off three times and the Steelers lost five fumbles, the last on the final play of the game.
Browns rookie quarterback Brandon Weeden sustained a concussion in the final minutes when he banged his head while falling awkwardly after an incompletion. Backup Colt McCoy, who suffered a concussion when the teams met late last season, came in and finished off the win without attempting a pass.
DOLPHINS 24, SEAHAWKS 21
At Miami, Dan Carpenter kicked a 43-yard field goal on the final play, capping a rally by Miami (5-6), which scored 17 points in the last 8:08.
Rookie Ryan Tannehill drove Miami 65 yards in the final 92 seconds to set up the winning kick. He finished 18 for 26 for 253 yards and a score.
Leon Washington returned a kickoff for a touchdown for the eighth time to tie the NFL career record and put Seattle ahead with eight minutes left. Miami answered with an 80-yard drive capped by Tannehill's 29-yard scoring pass to Charles Clay, making it 21-21.
The Seahawks (6-5), who are unbeaten at home this year, lost for the fifth time in six road games.
RAMS 31, CARDINALS 17
At Glendale, Ariz., Janoris Jenkins became the first player in Rams history and the first NFL rookie since 1960 to return two interceptions for touchdowns in the same game and St. Louis (4-6-1) handed the Cardinals (4-7) their seventh loss in a row.
Jenkins' returns of 36 and 39 yards emphatically ended the Rams' streak of five straight games without an opponent turnover. Arizona rookie Ryan Lindley was intercepted four times in his first NFL start.
Sam Bradford had a pair of 37-yard touchdown passes to Lance Kendricks and Chris Givens as the Rams snapped a five-game winless streak. Steven Jackson rushed for 139 yards in 24 carries.
JAGUARS 24, TITANS 19
At Jacksonville, Chad Henne threw two touchdown passes, sparking the NFL's worst offense for the second consecutive week.
The Jaguars (2-9) snapped a seven-game losing streak and were competitive at home for the first time this season.
Henne, making his first start in more than 13 months, found Cecil Shorts III on a 59-yard touchdown play in the third quarter and hooked up with rookie Justin Blackmon for a 7-yard score in the fourth.
The Titans (4-7) cut the lead to 21-19 on Jake Locker's 6-yard pass to Kenny Britt with 4:52 remaining and had the ball with a chance to take the lead. But Russell Allen tipped Locker's pass over the middle, and Dwight Lowery—back on the field after a five-week absence—had his first interception of the season.
