Men's Boxing Heavy 91kg Quarter-Finals - Full Bouts | London 2012 Olympics

📲 Subscribe to @olympics: http://oly.ch/Subscribe Full coverage of the quarter-final bouts in the men's (91kg) boxing event at the London 2012 Olympic Games. Boxing made its Olympic debut at the 1904 Games in St Louis, since then boxing has been staged at each edition of the Games, except in 1912 in Stockholm, owing to Swedish law, which forbade the practice. The rules have evolved since the 1980s: 1984 in Los Angeles: protective helmet obligatory; 1992 in Barcelona: set-up of an electronic scoring system to strengthen the objectivity of refereeing; 2007: standardised point scoring. Women's boxing will make its debut at the 2012 London Games in London.
