NEW YORK - The two conferences growing out of the old Big East are moving forward.

Butler, Creighton and Xavier will join the so-called Catholic 7 schools in the new basketball conference keeping the Big East name, a person familiar with the situation said Tuesday. The person spoke on condition of anonymity because the announcement will not take place until Wednesday, when it will be made in conjunction with a news conference on the league's broadcast deal with Fox.

Georgetown, St. John's, Villanova, Seton Hall, Providence, Marquette and DePaul left to form a new league for next season.

Meanwhile, their old colleagues announced a broadcasting deal with ESPN on Tuesday. The unnamed conference's contract for football, basketball and other sports runs through the 2019-20 season and pays about $20 million a year.

Along with a new name, that league still needs a conference basketball tournament site, a revenue-sharing system and a 12th football member. Temple will be a member of that conference.

The Catholic 7 negotiated to keep their basketball tourney in Madison Square Garden. Xavier and Butler are leaving the Atlantic 10, while Creighton departs the Missouri Valley Conference.

Butler spent just one season in the A-10, rising rapidly in the college basketball world after making the national championship game in 2010 and '11 out of the Horizon League.

Xavier has long been one of the top basketball programs outside what were the power six conferences.

Creighton is a No. 7 seed in this year's tourney.
