Late Saturday night, Chloe Kim revealed on Twitter she will need surgery to fix a broken ankle. The tweet came after Kim had finished second to fellow U.S. snowboarder Maddie Mastro at the Burton U.S. Open Snowboarding Championships.
It was unclear when Kim had broken her ankle, having laid down the best run of the semifinals at the U.S. Open event in Vail and was able to compete well enough in the finals to finish on the podium.
Mastro took the top spot in a run that featured the first double crippler ever landed by a woman in competition, according to VailDaily.
