When was "Third Saturday in September" first used to refer to the Florida–Tennessee football rivalry?
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.

The Gators beat coach Bill Alexander's Georgia Tech Yellow Jackets for the first time, handing them their worst defeat in years, 55 to 7. Red Bethea scored three touchdowns, Ed Sauls two, and John Hall one. After the Tech game, newspapers posted how Bethea "made the Florida fans forget there ever was a Cannonball Clyde Crabtree." 
The season's final game saw a bitterly fought contest end in a 13 to 6 loss to coach Robert Neyland's Tennessee Volunteers. Buddy Hackman scored both of Tennessee's touchdowns. Tennessee quarterback Bobby Dodd also starred.
