British boxer Chantelle Cameron knocked out of Olympic Games contention

British boxer Chantelle Cameron's Olympic dream is over after she was eliminated at the Women's World Championships in Kazakhstan.

The 25-year-old Northamptonshire lightweight, who needed a semi-final finish to qualify for Rio later this summer, lost a split decision to Finland's Mira Potkonen in the Astana preliminaries.

Ireland's Katie Taylor, who also needs to reach the last four to secure a spot for Brazil, progressed to the last 16 in the same weight division after a unanimous decision against Sweden's Agnes Alexiusson.

Britain's Nicola Adams, who has already qualified to defend her Olympic crown, began her quest for a first world title with a unanimous decision over Uzbek Dilnozakhon Odiljonova in the flyweight division.
