NASHVILLE – The Titans on Friday placed defensive back Elijah Molden and linebacker Chance Campbell on Injured Reserve.
Earlier in the day, Titans head coach Mike Vrabel ruled out Molden (groin) and Campbell (knee) for Sunday's game against the Giants.
Now, they'll miss at least four games.
Molden has missed a long stretch of practices after suffering the injury last month. Campbell, meanwhile, suffered his injury earlier this week in practice.
Molden and Campbell join receiver Racey McMath and tight end Tommy Hudson on Injured Reserve, along with outside linebacker Harold Landry, who isn't expected to return.
All players placed on injured reserve during the regular season are eligible to return. The number allowed to return to the active roster is capped at eight this season.
The Titans face the Giants on the regular season opener at Nissan Stadium.
