On December 6, 2007, Kelly was named the head coach of the proposed new All American Football League's Tennessee team. However, the league suspended operations March 12, 2008 (permanently, as things later developed, although only a delay was announced at the time), and Kelly signed with the Georgia Force two weeks later on March 26, 2008, but never actually participated in any games as an active player for the Force. Kelly retired as an Arena Football player following the 2008 season and currently serves as a commentator on Tennessee Volunteers football radio broadcasts.
