Gonzaga is set to join the Pac-12 Conference, sources told ESPN's Pete Thamel and Kyle Bonagura.
An official announcement is expected Tuesday, according to sources.
The addition of Gonzaga to the Pac-12 as a basketball school comes amid the conference's widespread football expansion. The Pac-12 also has added Utah State, Boise State, Fresno State, Colorado State and San Diego State in recent weeks.
