Florida–Tennessee football rivalry
Florida and Tennessee have played on the third Saturday of September almost every year since 1992, giving the rivalry its nickname. Notable exceptions were in 2001, when the game was postponed until December 1 due to the September 11 terrorist attacks, and in 2014, when the addition of two new members to the SEC temporarily scrambled the dates of many traditional conference rivalries and moved the Florida–Tennessee game to October. The rivalry has sometimes served as the conference opener and is often the first significant test of the season for one or both of the teams.
Auburn–Florida football rivalry
The University of Arkansas and the University of South Carolina joined the SEC in 1991, and the conference was split into two six-team divisions in 1992. Since then, Florida has been a member of the SEC Eastern Division, and Auburn has been a member of the SEC Western Division. At first, every SEC team played two games every year against two permanent rivals in the other division and a third cross-divisional game that rotated among the other four teams in that division. Auburn's original two cross-division rivals were Georgia and Florida; Florida's were LSU and Auburn. In 2002, the SEC changed the cross-division format to one permanent rival and two rotating teams. Since Auburn's rivalry with Georgia was even older, Georgia remained Auburn's lone cross-division rival while Florida retained their annual game against LSU, and the previously annual Auburn–Florida football rivalry became an intermittent one.
