The league will hold a media teleconference at 1 p.m. Wednesday, presumably to announce the news about the title game.
Brett McMurphy of ESPN tweeted from his verified account that sources told him the league is expected to begin holding a championship game in 2018.
The Sun Belt had been one of two FBS conferences not to hold a championship game, but the Big 12 announced last week it would be holding a championship game in the 2017 season.
This is an expected move for the conference after the NCAA voted in January to deregulate conference championship games.
