CHONGLI, Zhangjiakou - American free skier Marin Hamill's participation in the slopestyle final was in doubt after she collapsed in the landing of her last big jump in the qualification at Beijing 2022 here on Monday.

Medical staff at the scene told Xinhua, "Don't worry, she hurt her knee, a twist."

"She remains conscious," the staff member added.

Hamill left the Genting Snow Park venue in an ambulance.

The accident took place in the second run when Hamill, 20, was already guaranteed a final berth in her Olympic debut with her first-run score of 69.43 points.

Hamill laid down in the snow and could not move. The medical staff at the scene reached her immediately and offered emergency treatment.

Hamill had competed in the women's free ski Big Air competition in Shougang and finished 14th with 132.25 points.
