http://bleacherreport.com/articles/...00-anti-doping-violation-ufc-can-blame-itself When the UFC and USADA reached an agreement to conduct testing, the UFC inserted several vague clauses in the policy that gave them some control in the process. One of them was Article 5.7.1, which requires an athlete returning from retirement to give four months' written notice prior to returning, offering USADA a four-month testing window prior to the athlete stepping into the cage. UFC, however, added a proviso: that it may grant a waiver of the rule "in exceptional circumstances or where the strict application of that rule would be manifestly unfair to an Athlete." What might qualify as "exceptional circumstances," you ask? Well, take a pay-per-view with a round number, throw in a major draw and sprinkle in a questionable decision that hurt the event's marketability and there you go. To the UFC, Brock Lesnar and UFC 200 were an exceptional circumstance. That's all it took, and from the beginning, it was a dubious use for an unnecessary rule.
Lesnar's July 9th day of (not sure if pre or post fight) has also tested positive. Just a white boy whose jacked.
Respectable source, too. If you read his tweets, he says a follow up article will be popping up soon.
i think they like to build the suspense and keep the attention on their organization. there is no real other reason to not say so.
