Exum's injury will require reconstructive ACL surgery in his left knee. As is standard procedure with athlete injuries, Exum will get multiple other opinions on his injury and the best option for treatment.
Although no timetable has been set, it's also unlikely that Exum will play for the Jazz in the 2015-16 season.
At this point, the Jazz are far more concerned about Exum than they are how his absence might affect the team.
