A video leaked on Sunday in which Porzingis appeared to have blood on his face.
The Mavericks are reportedly investigating an altercation involving All-Star forward Kristaps Porzingis in Europe this past weekend, according to The Athletic's Shams Charania.
On Sunday morning, a video leaked in which Porzingis appeared to have blood on his face.
Charania reports Porzingis was "jumped at the club, assaulted and hit by objects" during the incident.
Tim MacMahon of ESPN.com reports that to the Mavericks' understanding, it was several Russians who attacked Porzingis and the object that was thrown at him might have been a chair. He added that Porzingis fought back before security broke it up.
