Another domino has officially fallen as NCAA conference realignment continues.

On Tuesday, Southern Miss announced that it will be joining the Sun Belt Conference. It wasn’t surprise news, as it had been expected that the Golden Eagles would be leaving Conference USA, which could have an uncertain future if more rumored moves come to fruition.

Everything started when Texas and Oklahoma announced its decisions to leave the Big 12 for the SEC. Since then, many schools have been switching conferences, as the Big 12 needed to find replacement programs and that started a ripple effect further down the spectrum.

Now, Southern Miss will be on the move as well after it had been a part of Conference USA since the conference formed in 1995. The only other original C-USA school still in the conference, UAB, is also leaving, as it will be joining the AAC.

The Sun Belt announced that Southern Miss will become a member no later than July 1, 2023. It will be the first school to join the conference since Coastal Carolina in 2016.

“This is a big day for our conference. We are thrilled to welcome The University of Southern Mississippi to the Sun Belt,” Sun Belt commissioner Keith Gill said in a statement. “Southern Miss brings a host of strengths to our conference. They are competitive across all of their sports, have a strong brand and are supported by a great fan base. The electric atmosphere surrounding their games is a tradition we are proud to now be a part of.”
