Iman Shumpert was stopped from entering the locker room of the Portland Trail Blazers after the Sacramento Kings' 115-107 victory.
Shumpert was angry with Jusuf Nurkic, who set a hard screen.
"Some stuff needed to be between me and him, a conversation between two men," Shumpert said. "Some stuff happened out there that we needed to have a conversation about. That's it."
Nurkic downplayed the incident.
"I'm not going to worry about it," he said. "He's going into retirement soon. I'm not going to worry about a guy who's going into retirement soon."
