Word on why WWE hasn't publicly announced the suspension of Andy Leavine is that they are going through the motions to make sure his Wellness failure is legitimate, like checking to see if he was prescribed something by a doctor or other steps along those lines. Andy also may be offered a second test but that's not confirmed. There have been situations where a talent failed a test, then took a second one and proved they were clean.
Andy reportedly failed his Wellness Test right before SummerSlam. It was also noted that Andy is still technically a developmental talent and WWE usually doesn't announce suspensions, releases or failures from developmental.
