Oakley was arraigned Tuesday in criminal court in Manhattan on misdemeanor assault and other charges before being released without bail.
Prosecutors have accused Oakley, 53, of striking a security guard in the fracas. They say two other people who intervened were pushed and received cuts.
Oakley says he'll fight the charges. He told The Associated Press in an interview this week that he didn't do anything wrong.
Oakley played for the Knicks from 1988 to 1998.
