Shayna Jack’s golden swimming comeback cut short by freak injury at worlds

• Australian won gold and silver before breaking hand in warm-up
• Mollie O'Callaghan wins her third medal at world championships

Australian swimmer Shayna Jack's world championships are over after she broke a hand in a warm-up area. Jack had collected gold and silver medals in relay events ahead of her scheduled individual swims at the world titles in Budapest but the 23-year-old, on return to international competition after a two-year doping ban, was hurt in a freak accident on Wednesday.

I'm broken-hearted to announce that I have to withdraw from the rest of the competition and that I won't have the opportunity to achieve everything I wanted to," Jack posted on Instagram. I am still so proud of what I've achieved, how far I've come with the amazing teammates I've been able to medal with."
