Here are three top plays from the Chiefs defense on Sunday:
If you read the title and assumed you were going to see a Ron Parker mention, you were right.
But for the sake of going in chronological order, let's start with the Chiefs' only sack of the game, which came in the second quarter.
The sack didn't come from the NFL leader in sacks, Justin Houston, but from the big man in the middle, nose tackle Dontari Poe.
1. Poe's sack on first-and-goal
The Chiefs defense has been making stands at the goal line all season long, and Sunday was no exception.
Midway through the second quarter and with the Chiefs trailing 7-3, the defense faced a first-and-goal situation from the 8-yard line against the Bills offense.
Poe fought his way past the center and brought down Bills quarterback Kyle Orton for a loss of six yards.
Just like that, first-and-goal from the eight became second-and-goal from the 14.
The Chiefs held the Bills to a field goal in what turned out to be a huge play in the game on the sack from Poe.
2. Parker's forced fumble of Bryce Brown
This is the most obvious top play from the game on either side of the ball.
With the Chiefs trailing 10-3 midway through the third quarter, Bills running back Bryce Brown takes the second-and-10 handoff from the 17-yard line 12 yards off the right side and has a clear path to the end zone. That's when Parker comes flying in from the right side and lays out to knock the ball away from Brown.
The ball bounces into the end zone and tight end Scott Chandler is unable to get possession of the ball before it rolls out of the back of the end zone.
Just like that, the Chiefs have the ball and dodge a major bullet that would have seen them in a 17-3 hole in the second half.
3. Parker's last stand
That Parker guy steps up again for the Chiefs defense.
With the Chiefs leading 17-13 late in the fourth quarter, the Bills had the ball deep in Chiefs territory.
The Bills had four chances to score from the 15-yard line with under four minutes to play and three of those passing attempts were thrown in the direction of Parker, who didn't allow a completion.
It was a defensive stand that will be remembered for a long time.
