Winter Olympic champion snowboarder Chloe Kim is to have surgery after breaking her ankle.
The 18-year-old American won silver at the Burton US Open on Saturday.
But on Sunday she said she had fractured her ankle, an injury she appeared to suffer in her first run at the event – but still went on to finish all three rounds of the contest.
“Unfortunately, I found out I broke my ankle today so I will need to get surgery to get it fixed,” she said.
