British halfpipe skier Rowan Cheshire remained 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 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.
