The Broncos took over at the Falcons’ 45-yard line after forcing Atlanta to go three-and-out from inside its own 10.
On the first play of the possession, Peyton Manning rolled out to his right and found Eric Decker who made a sliding catch for a gain of 18 yards.
Then, a Demaryius Thomas catch and a Willis McGahee run helped get the Broncos inside the 10-yard line.
On fourth-and-goal from the 2-yard line, Manning handed it to McGahee who took it in for the touchdown, his second of the night.
With 3:25 remaining in the game, Atlanta will take over with a 27-21 lead.
