UNDATED (AP) -- The San Francisco 49ers have won a rematch of last season's NFC divisional playoff game while beating the Green Bay Packers for the third straight time in 12 months.
Colin Kaepernick (KAP'-ur-nik) was 27 of 39 for 412 yards and three touchdowns as the Niners downed the Packers 34-28. Anquan Boldin was Kaepernick's prime target, catching 13 passes for 208 yards and one touchdown.
Green Bay led 28-24 until Frank Gore scored on a one-yard run with 5:47 remaining.
Jordy Nelson and Randall Cobb each over 100 receiving yards and one touchdown for the Packers as Aaron Rodgers passed for 333 yards, three TDs and one interception.
The New Orleans Saints welcomed coach Sean Payton back from his one-year bounty ban by knocking off the defending NFC South-champion Atlanta Falcons 23-17. Drew Brees (breez) passed for 357 yards and two TDs.
Brees tossed a 25-yard touchdown pass to Marques Colston, who set a Saints franchise mark for catches with 533. Brees also hit tight end Jimmy Graham for a 7-yard score in the third quarter.
Matt Ryan passed for 304 yards and two touchdown passes in a losing effort for the Falcons. Atlanta drove to the New Orleans 3-yard line in the final minute, but the drive stalled.
The Andy Reid era in Kansas City opened with a resounding victory as the Chiefs mauled Jacksonville 28-2. Alex Smith tossed a pair of early TDs and the Chiefs defense took over from there. Jacksonville was able to get past its own 36-yard line once, creating a downer for new Jags coach Gus Bradley.
Jamaal Charles ran for 77 yards and a touchdown before leaving the game with a quadriceps injury, but that was about the only negative for the Chiefs.
Tennessee's revamped defense sacked Ben Roethlisberger (RAWTH'-lihs-bur-gur) five times and the Titans shut down the Pittsburgh Steelers 16-9, holding the Steelers to just 195 yards at Heinz Field. Chris Johnson ran for 70 clock-chewing yards, Jackie Battle bulled his way to a 3-yard touchdown in the second quarter and Rob Bironas (bih-ROH'-nihs) kicked three field goals for the Titans.
Jim Trestman is a winner in his NFL coaching debut. The new Chicago Bears coach, a longtime CFL coach, guided his team to a 24-21 come-from-behind win over Cincinnati. Jay Cutler passed to Brandon Marshall for the go-ahead, 19-yard touchdown with 7:58 left in the fourth quarter. The Bengal blew a second-half 11-point lead.
The New England Patriots had a tougher-than-expected time in Orchard Park, N.Y., before finally nipping the Buffalo Bills 23-21 on Stephen Gostkowski's 35-yard field goal with five seconds left. Tom Brady set up the decisive score by leading a 49-yard, 12-play drive during which he twice completed passes to convert third downs. It was Brady's 36th career victory in which the Patriots were tied or trailed in the fourth quarter. Brady finished 29 of 52 for 288 yards passing and two touchdowns in helping the Patriots win their season opener for the 10th straight season.
The Indianapolis Colts won their season opener for the first time since 2009. Andrew Luck ran 19 yards for the winning touchdown in the Colts' 21-17 victory over Oakland. Luck was 18 of 23 for 178 yards with two touchdown passes. Oakland started Terrelle Pryor, who was 19 of 29 for 217 yards and one TD. He also broke the Raiders rushing record for a quarterback with 13 carries for 112 yards. But Pryor tossed a pair of costly interceptions in the red zone, including one in the final 25 seconds to seal Indy's win.
Geno Smith is a winner in his first start as New York Jets quarterback. Nick Folk kicked a 48-yard field goal with 2 seconds remaining after Buccaneers were called for a bad penalty. With the Jets trailing 17-15 and time running out, rookie Geno Smith scrambled for 10 yards -- and was shoved while he was out of bounds by Lavonte David. The 15-yard penalty gave the Jets the ball at the Buccaneers 30 and set up the winning field goal by Folk on the next play.
Reggie Bush was a hit in his debut with the Detroit Lions. Bush turned a short pass into a 77-yard touchdown in the third quarter and finished with 191 yards of offense to help the Lions pull away to beat the Minnesota Vikings 34-24 at Ford Field. The Lions were helped by Christian Ponder's four turnovers, including three interceptions.
Seattle opened with a 12-7 road win at Carolina as Russell Wilson threw for 320 yards, including a 43-yard fourth-quarter touchdown pass to Jermaine Kearse with 10:13 left. Until then, the Seahawks had managed just a pair of field goals. The Panthers' offense was even worse. QB Cam Newton was held to 125 yards passing and one touchdown, a 3-yard strike to Steve Smith in the first half.
