CHICAGO — The Chicago Bulls have suspended forward Bobby Portis for the first eight games for injuring teammate Nikola Mirotic during a fight at practice.

Mirotic suffered multiple broken bones in his face as well as a concussion on Tuesday. He will likely need surgery and is out indefinitely.

The team announced the suspension on Wednesday. Chicago opens the season at Toronto on Thursday.

A 2015 first-round pick, Portis has averaged 6.9 points and 5 rebounds. He will be allowed to practice with the team while he is suspended.

Mirotic averaged 10.8 points over his first three seasons with Chicago. A restricted free agent, he signed a two-year contract that could pay as much as $27 million in September. The club holds an option on the second season.
