A person with knowledge of the decision says East Carolina will join the soon-to-be-renamed Big East as an all-sports member, instead of just for football as originally planned.
The person, who spoke on condition of anonymity because an announcement would be coming later Wednesday, also says Tulsa will officially be added to the conference soon.
East Carolina had already been set to join Cincinnati, Connecticut, South Florida and the rest of the Big East football schools in 2014.
But with the recent split of the football and basketball schools, the football side has decided to give up the name Big East and needed to add more members for all sports.
Tulsa is expected to join by 2015, when Navy also comes aboard, and will give the league 12 schools.
