On Tuesday, October 17, Chicago Bulls forward Bobby Portis reportedly punched teammate Nikola Mirotic, fracturing multiple bones in his face and causing as concussion. Mirotic was hospitalized and will miss approximately 4-6 weeks after the incident.

According to the Bulls organization, Mirotic will be undergoing surgery for the fractures in his face. The specific fractures will not be named until Mitotic has fully recovered from the concussion. The team has said Mirotic will be out indefinitely, as they want him to fully recover. Mirotic will be a big factor in the Bulls’ offense once he recovers from the injury.

Mirotic, who recently signed a 2-year, $27 million contract to remain with the Bulls, played in 70 games in the 2016-17 NBA season, averaging 10.6 points with 5.5 rebounds. Portis, on the other hand, averaged a quiet 6.8 points, and 4.6 rebounds as he played in 64 games and 13 starts for the organization.

Bulls president and former-Bull John Paxson told reporters, “Bobby isn’t a bad person, he just made a mistake. Our responsibility as a team is to be supportive of Niko and Bobby moving forward.”

The team has not revealed a cause for the altercation.
