Spokeswoman Monica Munoz said Thursday the case will not be sent to the City Attorney's Office because the investigation found there wasn't enough evidence to prove that a crime occurred.
Munoz said the case has been inactivated. If any evidence comes to light that would indicate there was a crime, the case potentially could be reopened, she said.
Cromartie had been under investigation for assault with a deadly weapon.
Detective Gary Hassen said a witness claimed Cromartie threw a champagne bottle, but the player said it slipped from his hand.
A man sustained a cut to the back of his head, but nobody was hospitalized or arrested after the incident early on Nov. 23.
