Eileen Gu has said she suffered an injury following a “very terrible accident” while training in New Zealand.

Gu, who only resumed training last month after hurting herself at the Winter X Games in January, was training at the Cardrona Alpine Resort before the incident happened on Friday.

The Chinese freestyle skier posted on Weibo detailing the incident and said she had flown to Christchurch early on Saturday for medical imaging, which would reveal the extent of the injury she had suffered.

“Unfortunately, a very terrible accident occurred yesterday due to human error,” she said. “Hopefully I’ll be back on the snow soon, but I’m still waiting for final confirmation from the expert team.”

Eyewitnesses said Gu appeared to be seriously injured and needed to be taken to the hospital on a stretcher.

The two-time Olympic champion expressed gratitude to her friends for their support and enthusiasm both on and off the snow – and called for understanding from her supporters.
