Back under way at Arrowhead.

Chicago Bears 9-14 Las Vegas Raiders
The Raiders may be leading but quarterback Geno Smith has now thrown three interceptions after Tyrique Stevenson picks him off at the start of the second half.

The undefeated 49ers are now back within three.

Baltimore Ravens 10-20 Kansas City Chiefs
Image source, ReutersThat was the last kick of the half at Arrowhead, a half dominated by Patrick Mahomes and the Kansas City Chiefs.
Baltimore have struggled on offense, coughed the ball up a couple of times and looked generally 'off'.
But there's only 10 points in the game still...
Baltimore Ravens 10-20 Kansas City Chiefs
Tyler Loop crashes one through the uprights from 40 yards and that's a six-point swing on the brink of the interval.
From looking like heading 23-7 behind, the Ravens are instead just 20-10 adrift.
But the Chiefs get the ball first in the second half.
Baltimore Ravens 7-20 Kansas City Chiefs
Kansas City cannot punish that turnover - Harrison Butker misses a field goal from 40-odd yards.
Lifeline for Lamar Jackson who races upfield desperate to make amends - and he gets the Ravens into field goal range themselves.
Chicago Bears 9-14 Las Vegas Raiders
Caleb Williams hasn't really got going today. Two straight incomplete passes mean Cairo Santos comes out and he kicks his third field goal of the day, this time from 52 yards.
Baltimore Ravens 7-20 Kansas City Chiefs
From bad to worse for Baltimore.
Lamar Jackson crashes into his own offensive lineman and fumbles!
The Chiefs gratefully gather it - and Jackson slams his helmet to the sideline turf in anger.
Indianapolis Colts 10-13 Los Angeles Rams
What have we just seen in the Colts game?
Daniel Jones connects with Adonai Mitchell, the Colts receiver shakes off a tackle, takes the ball 75 yards to the goal-line and then... FUMBLES!
There is nobody around him, the ball simple slips out of his hand as he extends his arm, holding the ball one handed, to celebrate the inevitable touchdown.
Instead it is a touchback for the Rams.

Image source, Getty ImagesNot a good omen for the rest of the AFC when Kansas City can chug up and down the field like this.
They haven't really stalled - yes, they've had to settle for field goals but they haven't turned the ball over, they haven't had a three-and-out, they haven't looked messy.
Baltimore Ravens 7-20 Kansas City Chiefs
Patrick Mahomes, 30, becomes the youngest player to reach 250 career touchdown passes.
He peels off to the left and finds Isiah Pacheco to run in virtually unchallenged.
Mahomes broke Dan Marino's longstanding record with that score.
Jacksonville Jaguars 17-6 San Francisco 49ers
Both sides score field goals in the final minute of the opening half.
First Eddy Pineiro's 23-yarder for San Fran makes it 14-6.
But Trevor Lawrence, with 42 seconds to play with, gets the Jags within range, spikes the ball with two seconds left and Cam Little tucks away a 26-yard effort.
The 49ers were undefeated coming into tonight but that record is in serious danger.
Baltimore Ravens 7-13 Kansas City Chiefs
Patrick Mahomes gets out of the pocket and - with the Ravens fearing a trademark run - he instead slings a short pass to Kareem Hunt, who is inside the 10-yard line.
Big chance for the Chiefs to add to their lead before half-time - 1:45 left in the second quarter.
Chicago Bears 6-14 Las Vegas Raiders
Image source, Getty ImagesAshton Jeanty made his name in college with these kind of explosive plays and that's why the Raiders took him in the first round of the draft.
He's been a little stiffled so far this season but tonight he is showing exactly what he can do.
Speed, agility, power - it was all on display as he shakes off the tackles and takes it to the house for his second touchdown of the night.
Baltimore Ravens 7-13 Kansas City Chiefs
Two things to remember.
Baltimore scored first in this game - 13 unanswered points since.
These sides are both 1-2 after three games.
Chiefs not playing like a 1-2 side at the minute as Patrick Mahomes again finds Travis Kelce for a decent gain.
Chicago Bears 6-14 Las Vegas Raiders
Ashton Jeanty. 64 yards. Touchdown. Wow!
Chicago Bears 6-7 Las Vegas Raiders
Caleb Williams is handed great field position after his defence intercepts Geno Smith.
But, starting on the Vegas 24-yard line, the Bears progress just nine yards in a nine-play drive lasting over four minutes.
Cairo Santos boots a 43-yard field goal to put the Bears within one.
But wait a minute...
