Olympic snowboard champion Chloe Kim revealed that she had broken her ankle while competing at the U.S. Open in Vali, Colorado.
The newly minted world champion posted about her injury on social media, shortly after finishing second in the halfpipe competition (Saturday 2nd March 2019).
American star Kim added that she will need "surgery to get it fixed".
Kim's Record Run Ended
The injury is a double blow for the 18-year-old, who was beaten in the women's halfpipe finals by teammate Maddie Mastro.
It beings an end to Kim's run of eight consecutive victories which includes the 2018 Olympic Winter Games in PyeongChang.
Kim scored 84.62 points in Colorado but fell just 0.12 points shy of defending her U.S.Open title.
