The Switzerland women's curling team has been defeated by Canada 5-8, in a result that could have wider implications for Team GB's progress from the group stage.
Canada, with five wins out of five, are guaranteed a semi-final place, but Switzerland's defeat means that they are only one win ahead of Great Britain, who currently have a game in hand.
Meanwhile, Japan's 6-8 defeat to the United States puts them level on results with Great Britain, South Korea and China, as all four have won two games out of four.
Eve Muirhead's side will face the Japanese tomorrow.
In other results, the Russian Federation have gone down 4-8 against South Korea, while Sweden have narrowly beaten Denmark 7-6.
