Each team gave the ball away four times. Each team returned a fumble for a touchdown, with M. D. Jennings running one back for Green Bay. The Bengals blew a 14-point lead, and the Packers blew a 16-point lead in the second half.

Green Bay scored 30 consecutive points and still lost. It was the first time in 14 years that a team won after allowing an opponent to score 30 consecutive points in a game.

The Bengals secured the victory when Michael Johnson batted down Aaron Rodgers's fourth-down pass with 1:21 left. Rodgers completed 26 of 43 passes for 244 yards and a touchdown, but he was sacked four times and threw two interceptions.

Trying to put the game away, Green Bay went for it on fourth-and-1 at the Cincinnati 30. Johnathan Franklin was stripped of the ball at the line, Bengals safety Reggie Nelson picked it up and started to run but fumbled — of course — and Newman scooped it up and went the rest of the way.

TITANS 20, CHARGERS 17 Jake Locker threw a 34-yard touchdown pass to the rookie Justin Hunter with 15 seconds left as Tennessee rallied at home. The victory was the franchise's first over San Diego since 1992, when the team played in Houston as the Oilers and Mike Munchak, now the Titans' coach, was still playing for the team.

The Titans had lost nine straight to San Diego, but Locker threw a winning pass to Hunter, who made his first catch in the N.F.L.

Locker completed seven passes, to six receivers, for 94 yards on the winning drive.

RAVENS 30, TEXANS 9 Baltimore had scored 3 points in 27 minutes, with Ray Rice (strained left hip flexor) unavailable for the first time since 2008. But Daryl Smith provided a game-changing play, stepping in front of tight end Owen Daniels late in the first half, intercepting a Matt Schaub pass and running 37 yards for a touchdown to propel the Ravens at home.

Less than two minutes after Smith's pivotal score, Tandon Doss scored on an 82-yard punt return.

Baltimore had only 4 first downs and 65 yards of offense in the first half yet went to the locker room with a 17-9 lead.

BEARS 40, STEELERS 23 Chicago's defense forced five turnovers and scored twice as the Bears won at Pittsburgh. Ben Roethlisberger threw for 406 yards, and Antonio Brown had 196 receiving yards, but the Steelers still fell to 0-3 for the first time since 1986.

COLTS 27, 49ERS 7 Andrew Luck threw for 164 yards and ran for a 6-yard touchdown while facing his college coach Jim Harbaugh for the first time, and Indianapolis won at San Francisco. The loss was quarterback Colin Kaepernick's first at Candlestick Park as a starter.

Trent Richardson, acquired by the Colts on Wednesday, scored on a 1-yard run on his first carry.

Aldon Smith started for the 49ers, two days after he was arrested and jailed on suspicion of driving under the influence and marijuana possession. The 49ers' chief executive, Jed York, said Smith would miss Thursday's game at St. Louis and perhaps sit out longer.

Smith's fellow linebacker Patrick Willis sustained a groin injury in the third quarter that sidelined him for the rest of the game.

DOLPHINS 27, FALCONS 23 Ryan Tannehill lobbed a 1-yard touchdown pass to the rookie Dion Sims with 38 seconds left, and Miami rallied at home.

Miami fell behind by 10-0 and 20-10, but the Dolphins still improved to 3-0 for the first time since 2002, with Jimmy Wilson intercepting a Matt Ryan pass to seal the victory.

Atlanta lost despite advantages of 24-16 in first downs, 377-285 in yards and 5-0 in sacks.

PATRIOTS 23, BUCCANEERS 3 After slow starts to their N.F.L. careers, Kenbrell Thompkins caught two touchdown passes, and Aaron Dobson had seven receptions for host New England, which moved to 3-0 for the first time in six seasons.

Thompkins, an undrafted free agent, scored on plays of 16 and 5 yards in the first half. And Dobson, a second-round draft pick, led the Patriots with his 7 catches and 52 receiving yards.

LeGarrette Blount, traded by Tampa Bay in the off-season, led the Patriots with 65 rushing yards.

BROWNS 31, VIKINGS 27 Cleveland's third-string quarterback, Brian Hoyer, overcame three interceptions to throw for 321 yards and 3 scores. Christian Ponder ran for two touchdowns for host Minnesota, but he threw an interception, lost a fumble and took his sixth sack on the final play of the game.

In the second quarter, the referee Bill Leavy mistakenly penalized the Vikings after Coach Leslie Frazier tried to challenge a ruling on a muffed punt. (A rule change from the off-season meant the Vikings should have been charged a timeout but should not have been penalized the yardage.) It was the second big miscue for Leavy's crew in the season's first three weeks: in Week 1, San Francisco was given an extra third down against Green Bay.

SEAHAWKS 45, JAGUARS 17 Russell Wilson matched his career high with four touchdown passes — two each to Sidney Rice and Zach Miller — as host Seattle improved to 3-0 for the first time since 2006.

LIONS 27, REDSKINS 20 Detroit beat Washington away from home for the first time since 1935, a 21-game streak that was the second longest in N.F.L. history. Detroit's last road victory in the series was against the Boston Redskins, two years before the team's move to Washington.

Matthew Stafford threw for 385 yards for the Lions, who also took advantage of a pair of fourth-quarter bobbles.

The score was tied at 17-17 when Robert Griffin III fumbled at the end of a scramble as he dived headfirst instead of sliding. The Lions recovered and kicked the go-ahead field goal on their next drive.

A Redskins touchdown pass was then overturned when the video replay showed that Aldrick Robinson had lost control of the ball.

SAINTS 31, CARDINALS 7 Jimmy Graham caught nine passes for 134 yards and 2 touchdowns for host New Orleans, whose defense had four sacks and two interceptions of Arizona's Carson Palmer.

COWBOYS 31, RAMS 7 Tony Romo threw for three scores as Dallas won at home. St. Louis avoided the shutout with a 4-yard Sam Bradford pass to Austin Pettis late in the third quarter after an interception by the Cowboys was wiped out by a roughing-the-passer penalty.
