Two key Titans members of the defensive backfield — Pro Bowl cornerback Cortland Finneganand nickel back Vincent Fuller — suffered injuries during the loss to the Jets on Sunday and their status for the Jacksonville game is uncertain.
Finnegan injured a hamstring in the second half and Fuller suffered a broken right arm in the first quarter. Neither returned to action, leaving the Titans with a patchwork secondary.
After Fuller's injury, rookie Ryan Mouton stepped in at nickel back. Another rookie, Jason McCourty, replaced Finnegan at corner.
When McCourty cramped up in the fourth quarter, Mouton switched over to the cornerback spot opposite Nick Harper.
