Bobby Portis publicly apologized for punching Nikola Mirotic during a scuffle at practice.

"I'm wrong for what I did," Portis said prior to Saturday night's game. "I want to publicly apologize to Niko. I feel like I let my fans, the Bulls organization and, most importantly, my teammates down. This is not who Bobby Portis is."

Portis received an eight-game suspension from the Chicago Bulls.

Portis said he has tried to talk to Mirotic but has not heard back from him.

"I texted Niko. I called him. He didn't respond," Portis said.

Portis said he is not concerned about any legal action Mirotic might take.

"I'm not concerned about that at this point," he said. "I'm just trying to publicly apology to Niko and my teammates and [show] that I'm real sincere about the situation.

"Going forward, I want to make sure that me and Niko are cool and that we can be teammates again. And I'm pretty sure we can. We just have to repair this relationship."
