NASHVILLE, Tennessee ̵
Head coach Mike Vrabel said he does not expect Casey to be available when the Titans host the Colts on Sunday. Expect defensive lineman Bennie Logan to replace Casey in the starting lineup.
Casey's left knee knee-jerked in the left knee against Redskins on Saturday as he narrowed Adrian Peterson towards the end of the fourth quarter. The eighth defender of the eighth year was helped by the field and taken to the tent for further investigation. Casey took off his cushions and watched the Titans' final defensive position from the sideline.
Casey had previously appeared in the injury report for a knee injury and missed two days before the game in Washington. He was called to his fourth career as a Pro Bowl last week. He finished his season with seven sacks.
The Titans received good news about quarterback Marcus Mariota. Mariota suffered a spiked injury on Saturday, which is thought to be unrelated to the elbow injury that has limited his ability to capture football this season. Vrabel said Mariota feels better and will test his limb on Monday during team training.
