Still hungry for their first road win of the season, the Steelers traveled to LP Field to take on longtime and former divisional rivals the Tennessee Titans.  Scoring began early in the first quarter as the Titans took a 3-0 lead after Rob Bironas's 22-yard field goal.  The Steelers responded with Suisham's 29-yard field goal to tie the game 3-3.  The Steelers took the lead after Roethlisberger connected with Mike Wallace for an 82-yard touchdown pass to take a 10-3 lead.  The Titans drew closer with Bironas's 38-yard field goal to shorten the lead 10-6.  In the 2nd quarter, the Titans retook the lead with Jamie Harper's 1-yard touchdown run to make the score 13-10.  They would increase their lead with yet another Bironas field goal from 47 yards out to increase their lead 16-10 at halftime.  The Steelers moved down the field in spite of a 28-yard field goal to make the score 16-13 for the only score of the 3rd quarter.  In the fourth quarter, the Steelers retook the lead with Baron Batch's 1-yard TD run to make the score 20-16 and then increased their lead with Suisham's 52-yard field goal for a 23-16 lead.  After thinking all was lost, the Titans drove down the field for a comeback attempt.  Matt Hasselbeck threw a 5-yard touchdown pass to Kenny Britt to tie the game at 23-23.  After Suisham missed a game-winning 54-yard field goal, the Titans again drove down the field and ended the game with Bironas's 40-yard field goal to make the final score 26-23.  The loss to the Titans was the first for the Steelers since their 31-14 loss against them in 2008 which was also in Tennessee.  The Steelers fell back under .500 and sat at 2-3 and 3rd place in the AFC North while sitting at 0-3 in road games during this point of the season.
