The American Athletic Conference has voted to add Army into the league as a football-only member, sources told ESPN’s Pete Thamel on Wednesday, with the sides working toward the Black Knights joining in 2024.

Army will serve as a replacement for SMU, which is joining the ACC next year, to keep the AAC at 14 teams for football.

The football-only addition follows a similar arrangement to the one Navy has with the conference. Ensuring that the longstanding rivalry game between Army and Navy is played at the end of the college football season was an important detail to solve as part of Army’s addition.

A source told ESPN’s Heather Dinich that the Black Knights and Midshipmen will not face other in an AAC regular-season conference game and that the rivalry would continue as a nonconference matchup. In a scenario in which Army and Navy finish in the top two in the conference standings, matching them up in the league’s title game, they would play each other in back-to-back weeks — first for the AAC title, and then in the rivalry game the following week, the source said.

Army and Navy both play in the Patriot League in sports other than football.

A traditional matchup with Air Force in early November will stay part of Army’s football schedule, the source said.

Other schools had been discussed to join the AAC, but none gained significant traction and only Army had received outreach from the conference, sources told Thamel last month.
