Pittsburgh got off to a strong start, scoring a pair of touchdowns in the first quarter. Ben Roethlisberger found Antonio Brown for a 57-yard score to give Pittsburgh a 7-0 lead, and later in the period Ike Taylor extended that lead to 14-0 by intercepting an Andrew Luck pass and returning it for a touchdown.
The Colts got even in the second quarter with a pair of one-yard touchdown runs -- the first by Donald Brown and the second by Luck -- and then took a 17-14 lead on a 53-yard field goal from Adam Vinatieri as time expired in the first half.
The Steelers did not find the end zone in the second half, but they got four field goals from Daniel Hrapmann, and that was enough to secure the victory. The Colts' lone second-half score came in the third quarter on a four-yard touchdown pass from Drew Stanton to Griff Whalen.
