The Titans placed Campbell (undisclosed) on injured reserve Wednesday, Jim Wyatt of the team's official site reports.
Campbell was ruled out ahead of Sunday's 20-6 loss to Tampa Bay after he suffered an undisclosed injury pregame. While the nature and severity of this issue are still unclear, the 24-year-old will now be sidelined until at least the Week 15 contest versus Houston. Campbell's absence will leave the Titans thin on special-teams depth. In a corresponding move, the team picked up offensive lineman Calvin Throckmorton off waivers Wednesday.
