I'm pretty sure Coastal gets the lowest remaining seed after the play-in/elimination games and and Southern Miss gets the higher remaining seed of those 4. That's why it's TBD on the conference website.

So - if #10 App wins their first game, Coastal gets App (lowest remaining seed).
If #7 Texas State wins that game vs. App, then Coastal gets the winner of the 8/9 game - Arkansas State vs. GA Southern.
