Source - Six schools officially apply to join American Athletic Conference

The American Athletic Conference has received applications from six schools hoping to join the conference, and the AAC is expected to send them each a formal letter by the end of the week detailing the terms of expansion, a source with knowledge of the process told ESPN on Tuesday.

Florida Atlantic, Charlotte, North Texas, UTSA, Rice and UAB have each officially requested to join the AAC, a move that was first reported by Yahoo Sports on Monday.

It's the first step in the realignment process, which is expected to move quickly this week after the university presidents and their general counsels have time to review the terms.
