Last year's Bulls team was mediocre in the standings but had plenty of in-season drama. This year's group is off to a similar start.
The Vertical's Shams Charania first reported that Nikolic Mirotic and Bobby Portis got in an altercation at practice and Mirotic was taken to the hospital as a result. The two were apparently in a shoving match until Portis hit Mirotic in the face.
The Bulls confirmed the incident in a statement.
"Chicago Bulls forwards Bobby Portis and Nikola Mirotic had a physical altercation during today's practice," the team statement read. "As a result of the incident, Mirotic suffered a concussion and maxillary fractures. Surgery is likely required. Mirotic is out indefinitely.
"The Bulls are evaluating disciplinary action. An update will be provided when applicable."
Mirotic is listed at 6-foot-10, 238 pounds and Portis is 6-11, 246, so any fight between those two could cause some serious damage.
The Chicago Tribune's K.C. Johnson reported that Mirotic has headed home and has not one, but two broken bones in his face.
