Former Guns N' Roses star Duff McKagan has undergone sinus surgery to remove scar tissue which built up during years of cocaine abuse.
The Velvet Revolver rocker - who turned his back on substance abuse in the mid-1990s - checked into a hospital this month for a mystery operation, prompting some gossips to suggest the musician was once again taking drugs.
McKagan has now spoken out to dismiss rumors of a relapse and he's revealed the procedure was necessary to repair the damage caused by his battle with illegal substances.
He tells RockAAA.com, "Thank you all for the very nice well-wishes regarding my sinus surgery recovery. I do want to make it clear for those of you who may be wondering... The surgery was a result of scar tissue build-up from my cocaine use which ended sixteen years ago. I have not relapsed on cocaine."
