Boxing star Devin Haney can breathe a sigh of relief -- his felony gun charge has been dropped, TMZ Sports has confirmed.
The L.A. District Attorney says Haney's case was declined last week due to insufficient evidence ... but it was not announced until his court appearance on Thursday.
We broke the story ... Haney was out in Hollywood on July 12th when the vehicle he was riding in was pulled over for an unsafe lane change and failure to use a turn signal.
