Ten days before he was scheduled to fight top-ranked heavyweight Fedor Emelianenko, Barnett tested positive for anabolic steroids. Lost was one of the most highly anticipated heavyweight fights in the sport. In its wake: a mad scramble. The event, promoted by Affliction Entertainment, was canceled. The promotion shuttered its doors. Many fighters signed deals with Zuffa. As the business goes, this marked a monumental moment in the history of mixed martial arts.
