Vitor Belfort vs. Oscar De La Hoya Switched from Exhibition to Pro Match The upcoming boxing matchup between former UFC world champion Vitor Belfort and hall of fame boxer Oscar De La Hoya is now slated to be a professional boxing match after it was originally scheduled to be an exhibition and not count towards their boxing records. Belfort and De La Hoya will square off on September 11th in Los Angeles, and the California State Athletic Commission will regulate the bout and make it an official contest.
