With eight seconds remaining in the game, kicker Matt Prater trotted onto the field to attempt a 59-yard field goal.
He drilled it — right down the middle with room to spare.
And the game is now tied at 10 with just three seconds left.
The Denver defense forced a three-and-out after failing to recover an onside kick and Tim Tebow and the offense took over with 53 seconds left.
In seven plays the Broncos moved into Chicago territory and Prater came on for the game-tying attempt.
