Sonny Bill and sister join rare siblings club

World Cup star Sonny Bill Williams and his sister Niall joined the rare Olympic siblings club on Sunday when both were named in the New Zealand Sevens teams for the Rio Games. Sonny Bill, 30, has targeted the Olympics to add to his list of sporting triumphs, which include winning two rugby union World Cups with the All Blacks as well as success in rugby league and professional boxing. His sister Niall, 28, was a New Zealand touch rugby player for several years before switching to the tackle game in 2015. Sonny Bill made himself unavailable for Super Rugby and the June Test series against Wales this year to focus on the Sevens.
