NFL record: Pittsburgh Steelers down Houston Texans

The Steelers trailed 13-0 during the second quarter but exploded to life to score three touchdowns in the final 90 seconds of the half to claim the ascendancy at Heinz Field.

Pittsburgh quarterback Ben Roethlisberger threw for two of the TDs, but the standout was the six-pointer in between as Antonio Brown threw a three-yard pass to fellow wide receiver Lance Moore.

Prior to that, Roethlisberger found Martavis Bryant with a 35-yard TD pass, while they finished the half will all the momentum when the playmaker hit Le'Veon Bell wide out in the dying seconds.

Ryan Fitzpatrick had earlier put Houston on the board with an 11-yard TD pass to running back Alfred Blue, but they would struggle to penetrate the end zone thereafter.

Two Randy Bullock field goals built the Texans' lead before the Pittsburgh blitz put the hosts ahead at the half-time break.

Bullock's third three-pointer early in the last quarter brought Houston within eight points, but Shaun Suisham's second and third field goals - having earlier opened Pittsburgh's account - gave them a match-winning lead.

Fitzpatrick's second TD pass of the match, a one-yard gain to Arian Foster, gave them faint hope of launching a late-bid for a match-tying score, but their attempt to regain possession via an onside kick failed narrowly.

The Texans slip to a 3-4 record in the AFC South division, in which they sit second, while the Steelers remain third in the AFC North.
