The Utah Jazz confirmed everyone’s worst fears Thursday afternoon—point guard Danté Exum suffered a torn ACL in his left knee.

Exum, 20, was hurt while hooping with the Australian National Team in a game this week against Slovenia.

There’s no timetable for his return to action.

From the press release:

Exum suffered a left knee injury on Aug. 4 while competing for the Australian National Team in a game against the Slovenian National Team in Ljubljana, Slovenia. After returning to Salt Lake City, he underwent magnetic resonance imaging (MRI) at University of Utah Health Care’s Orthopaedic Center this morning. Following the examination, Jazz physicians Dr. Travis Maak and Dr. David Petron determined that Exum sustained a tear of the anterior cruciate ligament (ACL) in his left knee.

 

“First and foremost, our overriding concern is with Danté and his long-term health,” said Utah Jazz General Manager Dennis Lindsey. “We are continuing to work closely with our medical staff, Danté and his representation in order to reach an accurate diagnosis and recommended treatment so that we can provide him with the best possible care. We all know how hard he will work to make a full recovery and look forward to his return to play.”
