ARLINGTON, TEXAS // Matthew Stafford saw his defence start wiping out a 24-point deficit with interceptions returned for touchdowns midway through the third quarter, then he and Calvin Johnson took over from there, leading the Detroit Lions to a stunning 34-30 victory over the Dallas Cowboys.
A week after turning a 20-point half-time deficit into an overtime win, the Lions provided further proof they are a legitimate contender this season.
Detroit move to 4-0 and have won an NFL-best eight straight games. This also was their franchise-record fifth straight road win, avenging a loss here last November that had been their NFL-record 26th straight road loss.
Tony Romo and the Cowboys (2-2) continued to show there is no lead and no deficit too big for them. They blew a 14-point fourth-quarter lead for the first time in their franchise history in the opener against.

Aaron Rodgers threw for a career-high 408 yards, tied a personal best with four touchdown passes and rushed for two more scores as the Green Bay Packers remained unbeaten.

Bengals 23 Bills 20
At Cincinnati, Andy Dalton, the rookie quarterback, shook off a horrid first half and led his first comeback victory, culminating in Mike Nugent's 43-yard field goal as time ran out against the previously unbeaten Buffalo Bills.
Dalton threw a touchdown pass and ran 3 yards on a draw play, tying the game with 4:09 to go. He scrambled for a first down on the winning drive and Nugent ended it with his third field goal in front of the smallest crowd of Paul Brown Stadium's history.
The Bengals (2-2) overcame a 17-3 half-time deficit to end a 10-game losing streak against Buffalo (3-1).
49ers 24 Eagles 23
At Philadelphia, the 49ers surged back from a 20-point deficit for the victory.
Vick was not hampered by his bruised right hand, throwing for a career-high 416 yards and two touchdowns and rushing for 75 yards. But the Philadelphia defence fell apart in the final 30 minutes, and Frank Gore capped a 77-yard drive with a 12-yard TD run with 3 minutes remaining.
David Akers, the former Eagles kicker, who left for San Francisco as a free agent this summer, kicked the decisive extra point. His replacement, rookie Alex Henery, missed from 39 and 33 yards in the final period.

Texans 17 Steelers 10
At Houston, Arian Foster rushed for 155 yards and the winning touchdown in the fourth quarter as Houston overcame an injury to All-Pro Andre Johnson for the win.
Johnson left in the second quarter with a right hamstring injury and did not return though he was back on the sideline late to watch Houston (3-1) finish off the injury-plagued Steelers (2-2).
Ben Roethlisberger was under pressure all day and was sacked five times behind an offensive line missing two regular starters. The quarterback injured his left leg late in the game and left the stadium wearing a walking boot.
The Steelers lost running back Rashard Mendenhall (hamstring), linebacker James Harrison (eye) and defensive end Aaron Smith (foot) during the game.
Foster, the 2010 NFL rushing champion, finally looked healthy after weeks of nursing a left hamstring strain.
Patriots 31 Raiders 19
At Oakland, California, Tom Brady bounced back from a four-interception performance by throwing for 226 yards, two touchdowns and committing no turnovers.
Wes Welker caught nine passes for 158 yards and a score, BenJarvus Green-Ellis and Stevan Ridley adding rushing touchdowns and the Patriots (3-1) played a mostly mistake-free game after last week's surprising loss in Buffalo.
This time the interception that changed the game was made by New England instead of Brady making the error. Patrick Chung got a gift-wrapped pick in the end zone late in the first half when Jason Campbell inexplicably threw the ball right to the safety with no receiver in the area for the Raiders (2-2).
Redskins 17 Rams 10
In St Louis, Ryan Torain ran for 135 yards and a 20-yard score, and Washington held off a late rally by winless St Louis.

Titans 31 Browns 13
At Cleveland, Matt Hasselbeck's fresh start in Tennessee has his team off to an unexpected excellent start.
The 13-year veteran quarterback, who left Seattle as a free agent after a play-off filled decade, threw three TD passes in the first half and the safety Jordan Babineaux returned an interception 97 yards for a TD for their third straight win under Mike Munchak in his first year as coach.
Hasselbeck threw for 194 yards in the first half while helping the Titans (3-1) build a 21-6 lead.
The 36-year-old finished 10 of 20 for 220 yards - 26 on two completions after half time.
Saints 23 Jaguars 10
At Jacksonville, Florida, Drew Brees threw for 351 yards and a touchdown, Darren Sproles added 188 yards and New Orleans improved to 3-1.
The Saints scored TDs on their first two possessions and looked well on their way to reaching 30 points for the fourth consecutive week. But Brees threw two interceptions, and the Saints were forced to settle for three field goals in the second half.
It did not matter against the Jaguars (1-3), who have scored just 39 points this season. They have two touchdowns in rookie Blaine Gabbert's two starts.
Gabbert completed 16 of 42 passes for 196 yards, with a touchdown and an interception.
Bears 34 Panthers 29
At Chicago, Devin Hester set an NFL record with his 11th punt return for a touchdown and Matt Forte ran for a career-high 205 yards for Chicago (2-2).
Hester had earlier set up a TD run by Forte with a 73-yard kick-off return before he ran back a punt 69 yards in the second quarter to move ahead of Eric Metcalf on the all-time list. He performed three somersaults in the end zone with the lead at 24-10, but the celebration was a little early.
The Panthers cut the lead to four points at half time and had their chances to take the lead in the second half but came up short, spoiling coach Ron Rivera's return to Soldier Field.
Rookie Cam Newton threw for 374 yards for the Panthers (1-3) and Steve Smith passed Muhsin Muhammad as the team's leading receiver, finishing with 181 yards on eight catches. He now has 9,414 in his career.
Chargers 26 Dolphins 16
At San Diego, Philip Rivers threw for 307 yards and one touchdown and San Diego knocked out Miami quarterback Chad Henne.
Henne hurt his left shoulder at the end of a run on a broken play on the Dolphins' second possession and did not return. Although backup Matt Moore led the Dolphins to the game's first TD, Rivers' passing eventually overpowered the Dolphins (0-4).
Rivers threw a 55-yard TD pass to Vincent Jackson to tie the game at 7-7 late in the first quarter. Ryan Mathews' 48-yard gain on a screen pass set up Mike Tolbert's one-yard leap over the pile for a 20-10 lead for the Chargers (3-1) early in the third quarter.
Falcons 30 Seahawks 28
At Seattle, Matt Ryan threw for 291 yards, rookie Julio Jones caught 11 passes for 127 yards, and Atlanta held off a second-half rally by Seattle.

Giants 31 Cardinals 27
At Glendale, Arizona, Eli Manning threw two touchdown passes in a 58-second span late in the game to rally New York.
The scoring passes of two yards to Jake Ballard with 3:37 to go and 29 yards to Hakeem Nicks with 2:39 left came after the Cardinals (1-3) seemingly had taken control of the game 27-17 on Beanie Wells' third rushing touchdown of the game with 5:16 to go.
Manning completed 7 of 8 for 126 yards on the decisive drives as the Giants (3-1) won their third in a row. He finished 27 of 40 for 371 yards. Nicks caught 10 for 162 yards.
Wells rushed for a career-best 138 yards.
Chiefs 22 Vikings 17
At Kansas City, Matt Cassel hit Dwayne Bowe for a 52-yard fourth-quarter touchdown pass, Ryan Succop was perfect on five field-goal attempts and the Chiefs won their first this season.
Succop's accurate right leg had already staked Kansas City (1-3) to a 15-10 lead by the start of the fourth quarter when Cassel dropped back to pass. He saw Bowe get around Cedric Griffin, who had slipped just after the snap, and hit his Pro Bowl wide receiver in stride.
Bowe made a pirouette to get around the safety Jamarca Sanford, then broke Griffen's tackle as the cornerback tried to recover, and trotted the last couple of yards for the touchdown.
Minnesota are now 0-4.
Ravens 34 Jets 17
Baltimore scored three touchdowns on defence, all off turnovers by the New York Jets quarterback Mark Sanchez, and cruised to victory in a bizarre game that featured an NFL-record five returns for scores.
