Markkanen was complaining of soreness for three straight days, and that led to the team looking in to the issue a bit further and finding more problems. There is no specific play or incident that he or the team can point to that caused this, although, he did admit to attempting to play through the pain, which could've added to the severity of it.
This injury came off a 21-point night in the Bulls' 117-110 win over the Minnesota Timberwolves on Wednesday night, which was his best performance in weeks. He is averaging 15 points and 6.5 rebounds per game this season, and even fought with the medical team on Thursday to continue to play despite the MRI. He recently joined Ben Gordon and Kirk Hinrich as the only Bulls to make 100 or more three-pointers in each of his first three NBA seasons, but he will be on the sidelines while watching his team fight for a playoff spot. Entering Sunday, the Bulls are just three games behind the Brooklyn Nets for the eighth and final playoff spot in the East.
