PITTSBURGH (AP) _ James Conner ran for 109 yards and the go-ahead touchdown midway through the fourth quarter as the Pittsburgh Steelers stayed perfect by rallying past the Houston Texans 28-21. The Steelers improved to 3-0 for the first time in a decade by putting the clamps on the Texans in the second half. Houston managed just 51 yards and two first downs after halftime as an early 11-point lead vanished. The Texans dropped to 0-3. Steelers linebacker T.J. Watt collected a sack to win bragging rights over older brother J.J., a star defensive end for the Texans.
