Prosecutors have dropped the felony gun charge against Ezekiel Elliott's best friend -- at least for now -- after he allegedly tried to bring a loaded gun into an Ohio bar this past weekend.
TMZ Sports broke the story ... Alvarez Jackson was arrested in front of the Park Street Patio bar in Columbus on Friday night. Ezekiel was spotted with cops during the incident but he was NOT arrested, detained or accused of any wrongdoing.
Jackson -- who's been described by Sports Illustrated as Zeke's "best friend" -- was facing up to 5 years in prison on the illegal weapons charge.
