Kiffin said Sunday after the Bucs' loss to the Atlanta Falcons that he told players and his assistant coaches last week of his decision.
Tampa Bay coach Jon Gruden wished Kiffin well on Monday, saying it was a good decision for the veteran NFL defensive coordinator.
Tennessee officials refused to comment Monday on the announcement.
The 33-year-old Lane Kiffin was introduced as the Vols' new coach Dec. 1. He succeeds Phillip Fulmer, who was forced to resign after 17 years coaching Tennessee.
