Ben Roethlisberger threw for 226 yards and two touchdowns in the first game since Antonio Brown injured his calf, and the Steelers clinched a first-round playoff bye with a 34-6 win over the Texans. Roethlisberger threw passes to six players as Pittsburgh (12-3) romped over the lowly Texans (4-11) despite missing the NFL's leading receiver.
The Steelers led 20-0 at halftime after taking advantage of two turnovers by the Texans. Bell added a 10-yard TD run late in the third quarter and rookie JuJu Smith-Schuster made it 34-6 with an 18-yard touchdown grab in the fourth.
Bell finished with 14 carries for 69 yards and Smith-Schuster had six receptions for 75 yards.
T.J. Yates was 7 of 16 for 83 yards and a touchdown for the Texans, who lost their fifth straight game and for the eighth time in nine games.
The Steelers hurried and harassed Yates all day with Mike Hilton leading the way with three sacks and three quarterback hits, Cameron Heyward adding two and forcing a fumble. Hilton became the first cornerback with three sacks in a game since sacks became an official statistic in 1982.
The Steelers took a 10-0 lead when Roethlisberger connected with Justin Hunter on a 5-yard touchdown pass in the first quarter.
Pittsburgh added a 36-yard field goal on the next drive to push the lead to 20-0.
