Utah Jazz point guard Dante Exum suffered a torn ACL in Slovenia this week, putting his availability for the 2015-16 season in doubt.
Exum, 20, was injured while playing for the Australian national team against Slovenia in Ljubljana on Tuesday, the Jazz said Thursday.
Exum came to a jump stop in the middle of the lane, and his left knee buckled.
Exum, the fifth pick in the 2014 NBA Draft, averaged 4.8 points and 2.4 assists last season.
