Siobhan Haughey on Monday said she will miss the World Aquatics Championships in Budapest, saying she has been slowed by an ankle injury.

The Hong Kong double-Olympic silver medallist was due to compete in the 100-metre and 200-metre freestyle events.

“I’m sad to share that I will not be racing at the world championships this week,” Haughey said in an Instagram post.

“At such a high-calibre meet, I want to make sure I’m delivering high-level performances. Unfortunately, I’m not there yet,” she wrote.

She also said: “Getting through quarantine and lockdowns at the beginning of the year weren't easy.”

“Adding an ankle injury to a challenging year was really testing my character,” she added.

In December, Haughey was named best female swimmer at the Fina Short Course World Championships after winning two gold medals and a bronze, and setting a world record in the women's 200-metre freestyle.

The double-Olympic medallist is Hong Kong's most decorated swimmer, and the only local athlete who has ever held a world record in swimming.
