John Amaechi 'proud' at Jason Collins gay announcement

Former NBA player John Amaechi says he is "pleased and proud" at US basketball player Jason Collins's announcement that he is gay, but warns the sporting world is still "populated by dinosaurs".

Collins declared his sexuality in an article for Sports Illustrated, and has become the first active male athlete in a major American professional team sport to do so.

Amaechi, who himself came out in 2007 after retiring from the sport, admits it is "a big risk" to come out as gay in sport - but believes Collins is the "perfect spokesperson" to do so.
