Appalachian State and Georgia Southern will leave SoCon for Sun Belt

BOONE, NC ( - Two of the most prominent teams in the second tier of college football will be moving up, as Georgia Southern and Appalachian State are leaving the FCS' Southern Conference for the Sun Belt of the FBS, a source tells SB Nation's Steven Godfrey. Godfrey reports GSU will make the full move in 2015, with a transitional season in 2014 and no change to its 2013 schedule.

The Sun Belt wanted to bring in existing rivals, and the relationship between App State and Southern intrigued the conference, according to a source.

The Winston-Salem Journal's Tommy Bowman reported earlier Monday that App State will announce its move this week (Georgia Southern also has a presser scheduled for Wednesday).
