Thornton, listed with an ailing hip on the Titans' injury report, is still expected to play Saturday.
Meanwhile, starting center Kevin Mawae (elbow) and reserve defensive end Dave Ball (back) both missed drills again Thursday and have not practiced all week. Neither is expected to play Saturday.
Mawae said his day-to-day status hasn't changed.
Defensive end Kyle Vanden Bosch (groin) and defensive tackle Albert Haynesworth (knee) both took part in a full practice for a second consecutive day and are expected to play against the Ravens.
Starting cornerback Nick Harper, who has been battling a groin injury, was a full participant again Thursday as well.
