Conference USA and the Mountain West, set to form a football-only conference as early as next season, have asked the Big East to join them in what could be a 32-team league, the Boston Globe reported Saturday.
The proposal would allow the Big East to keep its automatic BCS qualifying status while giving the other two leagues access.
No conference officials were available for comment.
With Syracuse and Pittsburgh off to the ACC, the Big East has six schools. Several reports say it plans to invite Boise State, Air Force, SMU, Houston, Central Florida and Navy.
According to the Globe, the megaconference would comprise four divisions.
• West: Boise State, Hawaii, UNLV, Nevada, Fresno State, San Diego State, Utah State (from the WAC) and San Jose State (from the WAC).
• Mountain: Air Force, Wyoming, Colorado State, New Mexico, UTEP, SMU, Tulsa and Houston.
• Central: Marshall, Memphis, Southern Miss, Tulane, UAB, Rice, Temple (from the MAC) and Louisiana Tech (from the WAC).
• East: USF, Louisville, UConn, Rutgers, Cincinnati, UCF, East Carolina and Navy.
A 28-team version would not include San Jose State, Temple, Louisiana Tech and Navy.
West Virginia is not included because it's expected to go to the Big 12 to replace Missouri, which reportedly is set to join the SEC.
