British halfpipe skier Rowan Cheshire says she cannot remember much about her Winter Olympic training crash which left her unconscious.
The 18-year-old spent the night in hospital after falling heavily on her face at the Rosa Khutor Extreme Park in Sochi on Sunday.
She tweeted a picture of her bloodied face and wrote: "Wasn't the best day yesterday, still don't remember much!
"Thanks everyone for the lovely messages."
Cheshire, who won her first World Cup event in January and was considered an outside medal chance in Sochi, was scheduled to compete on Thursday.
A decision has not yet been made as to whether the teenager from Stoke-on-Trent can make her Olympic debut.
Team GB said she had had a restful night and was discharged on Monday. Her coach Pat Sharples had stayed with her overnight and Team GB skiers Katie Summerhayes and Chemmy Alcott visited her.
"Her progress will be monitored on a day to day basis as is standard with concussion and a determination regarding her ability to compete will be made later this week," said a Team GB statement.
International Ski Federation medical guidelines suggest athletes who have suffered concussion can return to action "after a minimum of six days".
But the final decision will made between Cheshire, chief medical officer Niall Elliott, performance director Paddy Mortimer and Alison Robb, freestyle skiing physio.
There have been a number of injuries at the Extreme Park, the worse being to Russian skicross racer Maria Komissarova, who broke her spine during training and underwent an emergency operation and is now recovering in hospital in Germany.
The IOC said it had no concerns about the course conditions and maintained there had been no more crashes and injuries than in previous Winter Games.
"Health and safety of the athletes is our number one priority," International Olympic Committee spokesman Mark Adams said.
"Winter snow sports are not without their risks, but we don't see any difference between this Games and the last one."
British teammate Murray Buchan trained on Monday in foggy conditions with James Machon and they will compete in ski halfpipe on Tuesday.
He told BBC Sport: "Rowan's OK, so all our thoughts are with her, and hopefully we'll see her soon.
"We've all come here to do a job, and compete at the highest level, and that's the way the sport goes sometimes - there are crashes, there are injuries and she would want us to keep skiing."
