British freestyle skiing halfpipe medal contender Rowan Cheshire has withdrawn from the Sochi Olympics after she sustained a concussion during a training crash, the British team said.
Cheshire, who is 18 years old, was regarded as a medal contender until she fell on her face during practice on Sunday and spent the night in hospital.
The skier, from Stoke-on-Trent, is unable to recover in time to compete Thursday, the British team's chief medical officer Niall Elliott said.
Wasn't the best day yesterday, still don't remember much! Thanks everyone for the lovely messages pic.twitter.com/qVG8eET3BV— Rowan Cheshire (@Rowan_C_) February 17, 2014
"With a concussion injury there needs to be a rest period followed by a graduated return to play phase. The time scale is unfortunately too tight for Rowan," he said.
Cheshire made a name for herself this season with strong performances in the World Cup, including her first win last month in Calgary.
