Utah Jazz point guard Dante Exum will be out of action for an undisclosed period after he injured his left knee while representing Australia in a warm-up match against Slovenia on Tuesday.
Exum suffered the injury when his left knee buckled as he was driving to the basket. The 20-year-old crumpled to the ground after rising up to take a shot and was subsequently helped off the court.
Exum is almost guaranteed to miss Australia's Olympic qualifier against New Zealand next week and there are concerns that he may also miss the upcoming NBA season if it is found that he has torn his ACL.
According to Basketball Australia, Exum "was treated by…medical staff at the game and will shortly travel to Utah for further medical assessment by his NBA team, the Utah Jazz."
The statement added: "The entire Basketball Australia family wishes Dante Exum well on his return to Utah and hopes for positive news on his injury."
Exum was the number five pick in the 2014 NBA draft and played all 82 games last season, averaging 4.8 points, 1.6 rebounds and 2.4 assists per game.
