[insert curse words here]
According to Andy Larsen of the Salt Lake Tribune, Dante Exum is expected to miss at least two more weeks due to a bone bruise caused by the ankle sprain from January. He had apparently sprained the ankle so badly that it caused the bone to bruise.
Just in: Dante Exum faces at least two more weeks of recovery time. In short, when he sprained his ankle against DET on 1/5, he sprained it hard enough to pick up a bone bruise. That bone bruise is now what's limiting his return, not the ankle sprain.
