I had mentioned the fact that Jacksonville state had announced a few months ago that they were looking for a game opening weekend and were willing to accept a guarantee.
There appears to be another "name" opponent available. - Sam Houston State
It has been announced that South Dakota will play at New Mexico on Sept 3 (replacement for Cal who is playing Hawaii in Australia). Sam Houston State was originally scheduled to play on Sept 3.
If this is the game, it is probably a home and home with a return to Texas in 2018 or 2019 (which is a 12 game season)
