A 24-year-old of Mequon, Wisconsin, was arrested on Oct. 20 for allegedly breaking a glass on a 27-year-old man's face.
The bar fight happened at Butch McGuire's bar at State and Division streets.
On Wednesday, the Cook County State's Attorney's Office dropped the charged against the man after insufficient evidence.
The man was facing a felony charge for aggravated battery.
On Oct. 22, prosecutors said shards from that broken glass caused cuts to victim's face and severed his jugular vein, which required surgery.
The man was released on the conditions that he does not have any contact with the victim or witnesses and that he stays away from Butch McGuire's, officials said.
