Jeff Fisher: Vince Young still starter
Young had three turnovers as the Titans lost 19-11.
"That defense has created some very difficult opportunities for a number of quarterbacks in this league year after year after year, even the most veteran quarterbacks," Fisher said. "This is his first opportunity against them. He'll get more opportunities against this defense, I'm sure."
Young was sacked and stripped of the ball after Chris Johnson missed a block, and the quarterback was slammed awkwardly to the ground by Steelers linebacker James Harrison. Young walked off the field to the sideline to boos.
Kerry Collins, who started the first six games last season before being benched for Young, warmed up. He went on the field for Tennessee's first series of the fourth quarter with the Titans trailing 16-3 to loud cheers from the crowd.
Collins was intercepted by Bryant McFadden to end his first series but tried to rally the Titans late.
Troy Polamalu helped eat up the clock by leaping over the line and tackling Collins for a loss on first-and-goal. Collins did toss a 2-yard touchdown pass to Nate Washington two plays later, and he found Kenny Britt for the 2-point conversion to pull within eight with 58 seconds left.
After Colin Allred recovered the onside kick for the Titans, McFadden broke up Collins' pass to Washington in the end zone with 13 seconds left. After two straight false starts by the Titans, Collins tossed a short pass to Johnson, who was tackled by Lawrence Timmons to seal the victory.
