Tulane will join the Big East in all sports, while East Carolina will join the league as a football-only member in 2014, sources told ESPN on Tuesday.
Tulane will make its official announcement at 2 p.m. ET, as will East Carolina at that time.
The reason the Big East opted for 13 schools in 2014 is that the league expects either Louisville or Connecticut to leave for the ACC, sources said. The Cardinals and Huskies are the favorites to replace Maryland, sources said.
The Big East has been in flux for more than a year. West Virginia, TCU, Syracuse, Pittsburgh, Notre Dame and Rutgers announced they were leaving, while Temple joined this year. Next season, Boise State, San Diego State, Memphis, UCF, Houston and SMU are scheduled to join the league.
Navy will join as a football-only member in 2015.
