WINNIPEG – Considering he’s a guy who’s usually already at a disadvantage by fighting guys who tower over him and weigh more, you may be surprised just how little Pat Barry cares about his fellow heavyweights using performance-enhancing drugs. Barry (8-5 MMA, 5-5 UFC) , who fights friend Shawn Jordan (14-4 MMA, 2-1 UFC) on Saturday’s UFC 161 pay-per-view main card, suffered a May 2012 loss to Lavar Johnson . The fan favorite then watched Johnson test positive for elevated levels of testosterone just two fights later. While fans were quick to surmise that Johnson may have been using banned substances in their fight too, Barry scoffs at the notion and quickly dismisses it. In fact, he said he doesn’t care if fighters are using them. He doesn’t, he said. But others? It’s of no concern.
