GB skier Cheshire hurt
British halfpipe skier Rowan Cheshire was knocked unconscious during training at the Rosa Khutor Extreme Park.
Cheshire, 18 and a genuine medal prospect in her first Olympics, fell heavily on her face on Sunday evening and had to be stretchered to a medical tent after remaining unconscious for several minutes.
Cheshire, who won her first World Cup title in Calgary last month to make her one of the leading contenders in Sochi, is due to compete on Thursday.
A Team GB spokesman said: "Halfpipe skier Rowan Cheshire was injured this evening during halfpipe training.
"She was immediately taken from the course and is currently at the polyclinic in the Mountain Village, where she is being evaluated by Team GB medical personnel."
Cheshire suffered concussion and will be kept in hospital overnight as a precaution and will be re-examined on Monday.
Cheshire's accident came at the end of a hectic day for medical personnel. The women's snowboard cross competition's Helene Olafsen of Norway and American Jacqueline Hernandez had to be stretchered off the course after accidents in qualification.
Swiss aerials skier Christopher Lambert was taken to hospital after suffering a suspected dislocated elbow in a heavy fall during training.
And worst of all, on Saturday Russian ski cross athlete Maria Komissarova sustained a broken and dislocated spine after a training accident and had to undergo a six-and-a-half-hour operation at a hospital in nearby Krasnaya Polyana.
