Muirhead on a high after leading GB into last four
Great Britain's women curlers will have a shot at a Winter Olympics medal after booking their place in tomorrow's semi-finals.
But Britain's men will have to negotiate a play-off against Switzerland today if they are to join them.
Skip Eve Muirhead steered her rink to a 6-5 win over Canada, who were eliminated as a result, and she feels Britain are gradually building momentum.
"It was a great team performance, it shows we have a lot of determination, a lot of patience and I'm really delighted to get the semi-final spot," she said. "The last few games we've got better and that's important."
After three straight wins, Kyle Smith's men's squad knew victory over the United States would secure a place in the last four, but they fell to a 10-4 defeat.
That means another victory over the Swiss is needed, Britain having beaten them already in their opening round-robin game.
Crowd-funded Great Britain bobsleigh duo Mica McNeill and Mica Moore, lying sixth after heats one and two, slipped to eighth after clocking 51.16 in heat three.
They held onto that position after their final heat, the highest ever placing by a British women's bobsleigh team at a Games.
Gold went to Germany's Mariama Jamanka and Lisa Buckwitz, with the USA's Elana Meyers Taylor and Lauren Gibbs taking silver and Canada's Kallie Humphries and Phylicia George the bronze.
Lindsey Vonn, meanwhile, described Sofia Goggia as "untouchable" after the Italian won women's downhill gold.
Goggia, the World Cup series leader this season, won by 0.09 seconds from Norway's Ragnhild Mowinckel as Vonn of the United States took bronze.
At 33, Vonn became the oldest women's alpine skiing Olympic medal winner in what she says is her final Games.
Vonn, who has 81 World Cup wins to date, said: "I skied really well, but Sofia is untouchable."
Evgenia Medvedeva set a figure skating short programme world record yesterday, but her mark was soon beaten by fellow Russian Alina Zagitova.
Medvedeva scored 81.61, but 15-year-old Zagitova was awarded 82.92 to lead the way. The concluding free skate takes place tomorrow.
Billy Morgan squeezed through to the men's Big Air snowboard final, but British team-mates Jamie Nicholls and Rowan Coultas are out.
Max Parrot of Canada led the way in qualifying in heat one with 92.50, as Coultas scored a best of 84.50 and Nicholls 81.25 to place eighth and 11th respectively.
Only the top six from each heat qualified for the final and Morgan improved his mark to 90.50 with his second effort. He stayed sixth to narrowly qualify for Saturday's final as New Zealand's Carlos Garcia Knight led the way overall with 97.50.
Morgan revealed his build-up had been far from ideal as he woke up with a blocked ear that had to be syringed.
British duo Andrew Musgrave and Andrew Young were sixth in their men's cross country sprint free semi-final in a time of 16:30.62 and missed out on a final place.
