NASHVILLE, Tenn. (AP) The Tennessee Titans believe their bye with the much-needed time off helped them heal for the final six games on the schedule.

How much remains to be seen. Coach Mike Vrabel didn't tip his hand Monday except to say he expected two of four Titans to test themselves when they practiced. But Tennessee doesn't have to share an injury report until Wednesday.

Tight end Delanie Walker and defensive tackle Jurrell Casey both think they're feeling good enough that there's a chance each might play Sunday when the Titans (5-5) host Jacksonville. Casey has missed the past two games with an injured shoulder, while Walker hasn't played since five snaps Oct. 20 against the Chargers.
