Bulls forward Bobby Portis has been suspended eight games for punching teammate Nikola Mirotic in practice Tuesday. Portis’ punch came after the two engaged in an altercation that involved shoving, and the blow landed Mirotic in the hospital with two broken bones in his face and a concussion. Mirotic is expected to be out weeks. Portis will be allowed to practice with the Bulls during his suspension. He’s one of four healthy Bulls big men.
