Chicago Bulls forward Bobby Portis has received an eight-game suspension for hitting teammate Nikola Mirotic and breaking his jaw at practice Tuesday.
Mirotic is out indefinitely after suffering fractures to his upper jaw and a concussion.
Portis will begin serving his suspension when Chicago opens the season Thursday night in Toronto. He will still be able to practice with the team during his ban.
The players had been talking trash to one another in practice, going back and forth before those exchanges escalated into a physical encounter, league sources told ESPN's Adrian Wojnarowski.
