General manager Ryan McDonough confirmed to Arizona Sports 98.7 FM that Chriss likely will not play when the Suns host the Charlotte Hornets on Sunday.
"He violated a team rule," McDonough said. "He probably won't be with us for the game tomorrow. He's a good kid who had a bad moment. We look forward to seeing him on Monday morning so we can turn the page and move on."
The incident occurred after Friday night's 129-97 loss to the Utah Jazz, according to sources.
An argument broke out over a postgame routine Chriss is required to do, sources said.
The second-year forward played 14 minutes in the game and scored three points.
Chriss is averaging 7.0 points per game this season.
