British halfpipe skier Rowan Cheshire will remain in hospital overnight under observation after she suffered a concussion in a training accident at the Rosa Khutor Extreme Park in Sochi on Sunday night.

Cheshire, 18, fell heavily on her face and, after remaining unconscious for several minutes, she was taken on a stretcher to a nearby medical tent, the Olympic News Service reported.

The British Olympic Association said Cheshire will continue to be monitored, with the Alsager-based athlete due to compete in the Olympic ski halfpipe event on Thursday.

"Team GB halfpipe skier Rowan Cheshire fell during halfpipe training this evening," read a BOA statement.

"She was attended to by the medical team at the halfpipe then taken to the polyclinic in the Mountain Village for further assessment.

"After examination by Team GB medical personnel it is confirmed that she has a concussion and, as a precaution, will stay at a local hospital overnight for further evaluation.

"She will be evaluated further during the coming days before a determination is made about her fitness to compete."

Cheshire is considered a medal prospect after winning her first World Cup title in Calgary last month.

Her injury came at the end of a day in which crashes littered the women's snowboard cross competition, with Norway's Helene Olafsen and American Jacqueline Hernandez 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.

On Saturday, Russian ski cross athlete Maria Komissarova sustained a broken and dislocated spine after a training accident. She underwent a six-and-a-half hour operation at a hospital in nearby Krasnaya Polyana.
