Watch the BBC's new iPlayer show The Whole 10 Yards
Los Angeles Chargers 10-14 Tennessee Titans
Frustrating for the Chargers as a fine drive - including a 38-yard completion to Keenan Allen - stalls at the Titans' nine-yard line.
Cameron Dicker converts the field goal to bring LA within four points.
Carolina Panthers 0-3 Green Bay Packers
Green Bay aren't able to take full advantage of that Xavier McKinney interception but they make sure they don't come away empty-handed, with Brandon McManus kicking a field goal from 49 yards to draw first blood.
Atlanta Falcons 7-14 New England Patriots
The Pats are back in front as rookie running back Terrell Jennings scores his first NFL touchdown with a three-yard rush.
Rhamondre Stevenson is out today for the Pats but in Jennings and TreVeyon Henderson they're covering that absences pretty nicely so far - New England have 63 yards on the ground from 13 rush attempts.
Chicago Bears 14-10 Cincinnati Bengals
Cincinnati settled for a field goal on their second possession before Chicago take the lead, with Caleb Williams picking out Olamide Zaccheaus with a 15-yard pass to cap a 74-yard drive.
Carolina Panthers 0-0 Green Bay Packers
Carolina have a lengthy drive overlapping the end of the first quarter and the start of the second.
But Green Bay's defence earns a stop with Xavier McKinney stepping up big.
First Bryce Young fumbles after being sacked by McKinney, and although the Panthers recover it, two plays later Young is intercepted by the Packers' safety.
Indianapolis Colts 7-0 Pittsburgh Steelers
Daniel Jones is looking to pass but the ball is stripped out of his hands for the fumble, and then recoverd by the Steelers.
And guess who!? Of course it's TJ Watt, who else would it be?
Denver Broncos 0-3 Houston Texans
Big worry for the Houdton Texans as CJ Stroud gets clobbered as he looks to slide after a scramble, but as can happen the diving defender flies in late and drills the quarterback in his chest and head area.
Kris Abrams-Draine was the offender in what looked a bad one.
Los Angeles Chargers 7-14 Tennessee Titans
Rookie Chimere Dike has had some highlight plays already this season and this is another.
He collects a punt, puts in a couple of hip swivels and takes it all the way to the house down the right-hand side of the pitch.
Titans back in front and frustrating the Chargers with TDs from an interception and a return.
San Francisco 49ers 14-7 New York Giants
San Francisco go in front as Mac Jones hits Jauan Jennings for an 11-yard score, with the big receiver dropping in short then turning and sprinting towards the corner and diving at the pylon, extending that huge frame for six.
Carolina Panthers 0-0 Green Bay Packers
Have to say, I'm a big fan of the Packers' throwback jersey. (That's my birthday present sorted!!)
But look at the helmets too. Check out that detail, making them look like the leather helmets they used to wear back in the day.
Anyway, wide receiver Savion Williams has coughed the ball up on Green Bay's opening possession, with Carolina recovering the fumble.

Sunday's late games
Denver Broncos 0-3 Houston Texans
We've had a missed field goal by Houston, then a blocked one from Denver, but now the Texans finally manage to convert a kick as Ka'imi Fairbairn nails his from just 23 yards out.
Some tough defence being played here by two of the best in the NFL this season - Bo Nix currently has ZERO passing yards...
Minnesota Vikings 14-7 Detroit Lions
The Vikings force the Lions to go three-and-out and JJ McCarthy then makes it two touchdowns from two possessions for the visitors.
This time the Minnesota quarterback finds tight end TJ Hockenson with a seven-yard scoring pass.
Atlanta Falcons 7-7 New England Patriots
Sometimes a play is executed too well there's nothing you can do, which is the case as Michael Penix floats a ball to Drake London for a Falcons touchdown in New England.
London's just too big for the cornerback as he leaps well above him to collect that jump ball.
Indianapolis Colts 7-0 Pittsburgh Steelers
Awful from the Colts special teams as they muff a regulation punt and hand Pittsburgh perfect field position - but the defence bails them out by stopping Aaron Rodgers as the Steelers go for it on fourth down from the four-yard line.
Mike Tomlin obviously feels three points aren't enough to keep up with the high octane Colts, but coming away with nothing after getting that big break seems a waste.
Chicago Bears 7-7 Cincinnati Bengals
Chicago make the perfect response to Cincinnati scoring with a kick-off return, and with a trick play to boot.
Caleb Williams leads the Bears up to the hosts' two-yard line and tosses the ball to one team-mate, who immediately tosses it to another, and it's DJ Moore who then lofts the ball to Williams in the end zone. What a play!
Los Angeles Chargers 7-7 Tennessee Titans
Image source, Getty ImagesIt doesn't take the Chargers long to level the scores - seven plays, 61 yards and it's fullback Scott Mattlock with the short reception from Justin Herbert.
His first career touchdown.
San Francisco 49ers 7-7 New York Giants
Image source, Getty ImagesWe've got a game brewing in the Big Apple as the 49ers hit back as Mac Jones throws a five-yard touchdown pass to a wide open Christian McCaffrey to tie it up at seven each.
Run CMC is so dangerous in these situations as both a runner and receiver, and when the Giants defence bites on the play-action to the right then he just strolls out to the left all on his own for the easiest of scores.
Minnesota Vikings 7-7 Detroit Lions
JJ McCarthy has returned from injury for the Vikings and after his rookie season was wiped out by injury, this is the young quarterback's first NFL game on a Sunday.
And he's made a decent start, capping Minnesota's opening drive with a 10-yard touchdown pass to Justin Jefferson.
Indianapolis Colts 7-0 Pittsburgh Steelers
They huffed and puffed, and looked like they'd missed their chance, but the Colts aren't the top scoring offence for no reason and they punch in a touchdown on fourth down with Daniel Jones driving over to score it himself.
The Steelers had batted away two pass attempts in the red zone to force a fourth down on the one-yard line, but this is a new Colts team and a new Daniel Jones - Indiana Jones as he's now known.
So they line-up quickly and Jones takes it himself on the QB sneak to open the scoring.
