Mikaela Shiffrin is on the brink of sensationally withdrawing from the Beijing Winter Olympics after failing to finish a second alpine skiing race in a row.
The 26-year-old double Olympic champion arrived in China ready to compete in five events, and was widely seen as the favourite to take gold in both the giant and women's slalom.
However, after crashing out of the former event this week, she made another critical early error in the women's slalom on Wednesday, and again failed to finish.
