Just found this from wikipedia while reading up on Mayweather has anyone ever seen this ??
In his semifinal bout against the eventual silver medalist, Serafim Todorov of Bulgaria, Mayweather lost by a controversial decision that the U.S. team officially protested. Many who saw the bout, including the referee, (who mistakenly raised Mayweather's hand when the decision was read) believed that Mayweather had won.[
