Team GB freestyle skier Rowan Cheshire has described the crash which ended her Sochi Winter Olympics as the "worst" of her career.
The 18-year-old was forced to pull out of the women's half-pipe after suffering a nasty fall during training on Sunday which left her unconscious.
"My head is still not 100%. I feel a bit foggy and a bit distant - like I'm in a dream," she told BBC Sport.
"I've had bad falls before but never done anything this serious, it's the worst I've ever had."
USA's Maddie Bowman became the sport's first Olympic champion in the final earlier this week.
