Where is it said that Jiri had the same infection in the second fight vs Poatan? He said in the first fight there was a lot of illness... But he never pointed to that before the fight. In the second fight, he said he was in shape, unlike in the first fight. Why'd he accept a second match vs Poatan if he said after the Rakić fight that for Poatan, he'd need to be even better than vs Rakić to win? Because he felt even better... But now he was seriously sick again?
That has nothing to do with what he meant by black magic. He said that totally in terms of Poatan being more focused than normally. He said that he realized that during Poatan's fight vs Hill, in which Poatan's focus and calmness didn't seem natural, seemed like he was fighting with transcendental things helping him in the octagon...
