According to Bouncer Chronicles UFC 200 suffered a major blow on Wednesday when Jon "Bones" Jones, who was set to fight Daniel Cromier in a rematch bout from UFC 182 in the main event, tested positive for a banned substance. UFC President Dana White said "This sucks. I don't know what to say. It's unfortunate."
This is the second time Jones tested positive for a banned substance. He tested positive for cocaine following his first win over Cormier in UFC 182. Former 10-time defending middleweight champion Anderson Silva heard about Jones being pulled from UFC 200 and asked his manager to ask about fighting Cormier on Saturday for a non-title fight.
