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

Mirotic suffered broken bones in his face as well as a concussion on Tuesday and will likely need surgery. Vice president of basketball operations John Paxson said Mirotic is expected to miss four to six weeks, and that he needs to clear the concussion protocol before the facial injuries can be resolved.

Paxson acknowledged fault on both sides while calling the incident “inexcusable.” He also called Portis “a good kid” who “made a mistake.”

The incident takes two more players out of their rotation, with newcomer Zach LaVine also missing the start of the season as he works his way back from a torn ACL.

WARRIORS: Forward Draymond Green underwent an MRI exam on his strained left knee and his status for an upcoming road trip is unclear.

Green got hurt in the closing seconds of the third quarter of Tuesday’s season-opening 122-121 home loss to Houston when he drove left to the basket, took an off-balanced shot and landed awkwardly. He came up hobbling and grabbing at his knee.

ROCKETS: Guard Chris Paul sat out Houston’s game in Sacramento on Wednesday night because of a bruised left knee.
