NASHVILLE, Tenn. -- Tennessee Titans starting defensive tackle Sen'Derrick Marks is doubtful for the regular-season opener against the New England Patriots after missing his third straight practice Friday with a sprained right knee.
Marks missed the preseason finale against the New Orleans Saints. Reserve offensive tackle Mike Otto is the only other player who did not practice and has been declared out as he recovers from hand and knee surgeries.
Defensive end Scott Solomon practiced for the first time Friday after having his right knee scoped last week and is questionable. Linebacker Zac Diles (hamstring) and defensive tackle Jurrell Casey (elbow) have practiced all week and are questionable.
The Titans announced Jake Locker and guard Steve Hutchinson are offensive captains and cornerback Jason McCourty and linebacker Colin McCarthy are defensive captains. Tim Shaw is special teams' captain.
