Looks like the Atlantic Sun and WAC are making a move to combine and join FBS, adding 10 teams over the next several years going from FCS to FBS. If it works as they intend that will make for the 11th conference in FBS
The WAC schools are - Stephen F. Austin, Abilene Christian, Utah Tech, Southern Utah, and Tarleton State
The Atlantic Sun schools are - Austin Peay, Eastern Kentucky, Central Arkansas, and North Alabama
Those 9 schools are aiming for 2024 in the FBS.
UT Rio Grande Valley is starting a program from scratch and hopes to be added in 2025 making the 10th school in the conference.
Sam Houston from the WAC and Jacksonville State and North Alabama from the Atlantic Sun are not making the jump from FCS to FBS, at least at this time.
