After trailing 19-14 one minute into the fourth quarter, the Broncos stormed back with 17 unanswered points to open the season with a 31-19 victory over the Pittsburgh Steelers. Facing a five-point deficit after a Pittsburgh touchdown, Manning marched the Broncos 80 yards down the field, then added a two-point conversion to take a 22-19 lead.
Denver’s D forced a three-and-out on the next Pittsburgh possession, and the Broncos then moved down the field to set up a 26-yard field goal by Matt Prater that made it 25-19.
The Broncos defense delivered the knockout punch on the following series when cornerback Tracy Porter jumped a route on the sideline and sped 43 yards into the end zone for a 31-19 lead that the Steelers were never able to threaten.
Neither team was able to produce much offense in the opening quarter, but both Ben Roethlisberger of the Steelers and Peyton Manning of the Broncos came alive in a back-and-forth battle that the Steelers led 10-7 at halftime and the Broncos led 14-13 going into the fourth quarter.
