Affliction “Trilogy”
Of all the positive PED tests on this list, Barnett’s second career failure might have had the greatest consequences for the broader outlines of mixed martial arts. With Barnett being a known, two-time offender, the California State Athletic Commission determined it would administer a random test prior to his scheduled bout with Fedor Emelianenko at the third Affliction event.
Alas, that fight was not to be. Barnett tested positive for the anabolic steroid drostanalone, and, in the absence of a suitable replacement, Affliction was forced to cancel the entire event. Aside from Bellator MMA’s lone venture into the pay-per-view business, Affliction was the last organization to really attempt to break into the UFC’s market share. Barnett’s positive test ended a potentially fruitful if likely unsustainable business model in the MMA industry.
