The Broncos began the second half with the ball looking to increase their 18-point lead. 80 yards and nearly six minutes later, Denver accomplished that goal with a remarkable Demaryius Thomas touchdown catch.
Running back Knowshon Moreno ran the ball on the first two plays of the drive and gained 12 yards.
Running back Lance Ball took it on the next two plays, gaining 6 yards and then breaking free for a 22-yarder.
In Chiefs territory, quarterback Peyton Manning connected with Thomas for the fourth time of the game, this time gaining 9 yards to the Kansas City 31-yard line.
The next pass was also to Thomas, picking up 11 to the K.C. 16.
Two plays later, Denver faced a third-and-7. Manning lofted one towards Thomas in the back of the end zone. Thomas leaped in the air and made a high-flying, one-handed touchdown snatch.
The score put Denver up 28-3 early in the third quarter. It also moved Manning past Brett Favre with his 73rd career game with three touchdown passes or more.
Thomas now has a game-high six catches for 86 yards and a touchdown after hauling in three passes on the drive.
Manning is 20-of-25 for 251 yards, three touchdowns and a passer rating of 148.1 to this point.
