This is gunna be interesting to see, we know Fury failed a drug test according the BBofC and we know Wilder has opponent take stringent test hence why two of them have failed already.
He passed VADA against Wlad back in 2015, but almost nobody knew he was caught about 5 months prior. If he gets caught again, I hope we know it in time at least and don't play the public and opponent for 1.5 years like last time out.
