Hockey East members voted on Wednesday to invite Connecticut to be the league's 12th member, according to multiple reports.
UConn, which currently plays in Atlantic Hockey, is expected to accept the invitation, with a formal announcement likely coming next week.
Notre Dame will become Hockey East's 11th member in the 2013-14 season. UConn is expected to join in 2014-15, according to the reports.
Commissioner Joe Bertagna told The Associated Press in May that UConn had become a target for expansion.
"Our attention is pretty focused on the University of Connecticut," Bertagna said. "There are other institutions that have had casual conversations. But I think it would be disingenuous to suggest that there is someone else, that our conversations are this far along."
