Nets CEO Brett Yormark reportedly shouted at a fan wearing a paper bag over his head on Monday night.
Yormark left his courtside seat at the Izod Center in the second half of New Jersey's 99-89 loss to Miami. He doubled back toward the fan, identified by the New York Daily News as Chris Lisi of New Jersey.
Then Yormark, Lisi and a friend of Lisi's got into a shouting match.
The Nets are 7-63 and extended a franchise record with their 14th straight loss at home Monday.
