PITTSBURGH — Tennessee’s revamped defense sacked Ben Roethlisberger five times and the Titans shut down the Steelers.
Chris Johnson ran for 70 clock-chewing yards, Jackie Battle bulled his way to a 3-yard touchdown in the second quarter, and Rob Bironas kicked three field goals for the Titans. Tennessee’s new-look defense did the rest.
Pittsburgh managed just 195 total yards and lost a series of players to injury, including Pro Bowl center Maurkice Pouncey. Pouncey left in the first quarter with a right knee injury and likely will miss an extended amount of time.
The Titans gave up more points than any team in the NFL last season and brought in Gregg Williams as an assistant. His impact was immediate. Roethlisberger completed 21 of 33 passes for 191 yards and a late touchdown, but never got comfortable when the game was in doubt.
SEAHAWKS 12, PANTHERS 7
CHARLOTTE, N.C. — Russell Wilson threw for 320 yards for Seattle, including a 43-yard touchdown pass to Jermaine Kearse in the fourth quarter.
The Seahawks managed just two field goals before Kearse beat cornerback Josh Thomas down the right sideline for the go-ahead score with 10:13 left.
The Panthers held Marshawn Lynch to 43 yards rushing, but Wilson picked up the slack by completing 25 of 33 passes.
The Panthers threatened to take the lead late, but safety Earl Thomas forced DeAngelo Williams to fumble at the Seattle 8. Defensive tackle Tony McDaniel recovered with 5:25 left. The Seahawks ran out the clock from there.
Carolina’s Cam Newton was held to 125 yards passing and one touchdown, a 3-yard strike to Steve Smith in the first half.
DOLPHINS 23, BROWNS 10
CLEVELAND — Ryan Tannehill passed for 272 yards and a touchdown, leading the Dolphins to a win over the Browns, who fell to 1-14 in Week 1 since 1999.
Tannehill, who was given more offensive weapons for his second NFL season, threw a 34-yard TD pass to Brian Hartline in the third quarter and drove the Dolphins to a game-clinching TD in the fourth.
Daniel Thomas had a 1-yard scoring plunge with 6:48 left, putting the Dolphins up by 10.
Miami’s Cameron Wake had 2½ sacks and the Dolphins’ defensive line sacked Brandon Weeden six times.
