Video of the aftermath of the incident obtained by TMZ showed an agitated Porzingis in a torn shirt, pushing someone out of the way and approaching a group of men before several people stopped him and urged him to calm down.
The 23-year-old Porzingis was acquired by Dallas in a blockbuster deal with the New York Knicks before the trading deadline but hasn't played for the club. He missed the 2018-19 season after tearing a ligament in his left knee in what turned out to be his final game for the Knicks in February 2018.
Porzingis will be a restricted free agent July 1, and the Mavericks have said they intend to sign him to a long-term contract.
