UNDATED (AP) – The Pittsburgh Steelers held on to win a battle of the AFC’s last two undefeated teams. Ben Roethlisberger threw two touchdown passes to Diontae Johnson while the Steelers were building a 27-7 lead in a 27-24 win over the Titans in Tennessee. Benny Snell Jr. added a 1-yard TD run, and Ray-Ray McCloud set up a touchdown with a 57-yard punt return. But the Titans scored 17 unanswered points in the second half and were in position to force overtime until Stephen Gostkowski missed wide right from 45 yards with 14 seconds left. The Steelers improved to 6-0 for their best start since 1978, when Pittsburgh won its first seven on the way to the Super Bowl. Ryan Tannehill threw for 220 yards and two TDs for the 5-1 Titans. Pittsburgh is now the NFL’s only unbeaten team following Seattle’s 37-34 overtime loss at Arizona.
