The error provoked howls of outrage throughout the Twitterverse and beyond.
Demetrious Johnson was announced as the split-decision winner of his UFC flyweight championship tournament semifinal bout against Ian McCall at March's UFC on Fox 2 in Sydney.
Only, he wasn't the winner. A scoring error was later discovered. The bout was actually a majority draw. By that time, it was too late to bring the fighters back to the Octagon, depriving fans of what promised to be an epic fourth-round overtime.
