Alexander was taken off the court on a stretcher after sustaining an apparent injury to his left side in the fourth quarter of Monday's 80-63 Summer League win over the Bulls, K.C. Johnson of Chicago Sports Network reports.
Alexander was seen moving around a bit on the stretcher, though he repeatedly grabbed at his left side and appeared to be in significant pain as he was taken off the floor. His next opportunity to suit up will come Wednesday against the Spurs.
