He will join Brandon Ashley, Rondae Hollis-Jefferson, and Stanley Johnson at the combine.
Good news for T.J. McConnell -- though he initially was not invited to the NBA combine (while all of Arizona's early entry candidates were), McConnell was invited to the NBA combine at the last minute according to DraftExpress:
Arizona senior point guard T.J. McConnell (@iPass4Zona) got a last-minute invite to the 2015 NBA Draft Combine.

This is big for T.J.'s NBA chances. He currently is not projected to be drafted by NBADraft.
