Phil Davis knows Saturday’s UFC 163 win over fellow light-heavyweight contender Lyoto Machida was a controversial one – even if the bout hadn’t taken place in his opponent’s home country, where Brazilians occasionally are gifted decisions. So when it comes to the type of close unanimous-decision victory he picked up at Rio de Janeiro’s HSBC Arena, Davis said he understands that it may be unpopular with many fans. “Fighting is an emotional thing,” he said after the pay-per-view co-headliner. “If I had lost this fight, I would be like, ‘I didn’t lose that fight, and they know it.’ That’s how it is. You put all you have into it. So everyone who was a Lyoto fan, I understand where you’re coming from
