Bryant takes the game-day roster spot of Justin Brown, who is inactive for the first time this season. McCullers, who is also a rookie, is dressing with starting nose tackle Steve McLendon out because of a shoulder injury.
The Steelers will wait another week to bring back Ryan Shazier, who has been out since spraining his right knee in a Sept. 21 game.
Shazier, who ran on the field before the game and tested his knee under the watchful eye of trainers John Norwig, joins McLendon, cornerback Ike Taylor (forearm) and Shamarko Thomas on the Steelers’ inactives list because of injuries.
Texans outside linebacker Jadeveon Clowney will miss his sixth consecutive game because of a right knee injury. Clowney, the No. 1 overall pick of the 2014 NFL draft, tested his knee before the game but the Texans will err on the side of caution.
