She was suspended from the Australian team and sent home from its pre-worlds training camp in Japan. The governing body had initially declined to elaborate on the reasons for Jack’s withdrawal. Swimming Australia CEO Leigh Russell says the governing body is “bitterly disappointed” about Jack’s positive test while adding that the matter has yet to be determined. Russell says the group will continue to provide appropriate support for Jack.
