CHICAGO – This morning they seemed like a team ready for a fresh start with primarily new group of players.

That appears to have changed at some point during Tuesday’s practice, when forwards Nikola Mirotic and Bobby Portis were involved in an altercation.

The Bulls released a statement confirming reports that circulated around 5 PM about the incident at the Advocate Center.

“Chicago Bulls forwards Bobby Portis and Nikola Mirotić had a physical altercation during today’s practice,” said the team in a statement released after 6 PM on Tuesday. “As a result of the incident, Mirotić suffered a concussion and maxillary fractures. Surgery is likely required. Mirotić is out indefinitely.

The Bulls are evaluating disciplinary action. An update will be provided when applicable.”

Reports have begun circulating as to what happened during the practice, mainly that the injuries to Mirotic came because of a punch from Portis to the face.

Mirotic was getting ready to start his fourth season with the Bulls and was entering training camp after signing a two-year, $27 million dollar contract with the team. Used primarily in a reserve role in 2016-2017, Mirotic averaged 10.6 points per game in 24 minutes of action.

The first round pick of the Bulls in 2015, Portis was getting ready to begin his third season in Chicago after starting 13 games last season. He averaged 6.8 points and 4.6 rebounds per game, which were slightly down from his rookie season.
