Titans MLB Zac Diles (broken leg) and LB Patrick Bailey (broken ankle) are both likely out for the season after going down in Week 7. Bailey is a core special teamer. Diles had taken over as Tennessee's starting middle linebacker during Colin McCarthy's recovery from a recurring high ankle sprain. McCarthy is expected to return in Week 8 against the Colts, so the Titans shouldn't feel Diles' loss other than from a depth perspective.
