Sophomore forward Luke Harangody will miss three to six weeks with a torn ligament in his right thumb, Irish coach Mike Brey announced in a statement Wednesday.
Harangody was injured in practice Monday, the statement said. Doctors evaluated him on Tuesday and determined the ligament was torn.
The statement said Harangody will be re-evaluated after three weeks.
"A timetable for his return has yet to be determined, but doctors and men's basketball trainer Skip Meyer will evaluate the situation in three weeks," it said.
At minimum, the sophomore will miss Notre Dame's first exhibition game against Saint Ambrose on Nov. 2. If Harangody is held out for a full six weeks, he will also miss the second exhibition game against Saint Edward's, as well as the opening game of the season against Monmouth and the team's trip to the Virgin Islands for the Paradise Jam tournament.
Harangody averaged 11.2 points and 6.2 rebounds per game last season. He also had seven double-doubles.
