Bulls forward Mike Dunleavy successfully underwent a low back microdiscectomy procedure earlier today at Rush University Medical Center. Dunleavy had experienced some occasional back discomfort over the summer which had recently worsened. Conservative measures failed to satisfactorily resolve his symptoms, therefore, the decision was made to perform the surgery. The timing is unfortunate, but it was imperative that all conservative measures were exhausted prior to making this decision. He is expected to be out 8-10 weeks.
