American star Mikaela Shiffrin says there is “no cause for concern” and was “sorry to scare everybody” after crashing out of the giant slalom in Killington, Vermont.

The two-time Olympic champion had been seeking a record-extending 100th World Cup win and looked well placed to reach the milestone before falling and crashing into safety netting on her second run.

Shiffrin, 29, left the slope on a rescue sled before being assessed at a medical clinic.

She was leading after the first run and had looked set for victory before the accident.

“Not really too much cause for concern at this point, I just can’t move. I have a pretty good abrasion and something stabbed me,” she said in a video posted on social media.

“I am so sorry to scare everybody and it looks like all scans so far are clear, so thank you for the support and concern.”

She added she would not be taking part in Sunday’s slalom event, which she has won six times out of seven at Killington.

Sweden’s Sara Hector, the reigning Olympic champion, won Saturday’s giant slalom.

“It’s so sad of course for Mikaela, a crash like that after she was skiing so well. It breaks my heart,” she said.
