Team GB must win a play-off against Switzerland to reach the men’s curling semi-finals after a disastrous end to their round-robin campaign saw them lose 10-4 to the USA.
GB were trailing 5-4 going into the seventh end, but an error from Kyle Smith saw the US take four stones against the hammer in the eighth.
The mistake led GB to concede the match, and they must now dust themselves off and beat Switzerland in Thursday’s play-off to reach the semis.
The winners will join Sweden, Canada and the US in the last four.
Earlier in the day, Team GB’s women curlers advanced to the semi-finals after edging out reigning champions Canada 6-5 in their final round-robin encounter.
a tense affair saw Eve Muirhead’s side trail 5-4 going into the final end, but GB scored two stones to qualify for the semis and knock Canada out of the completion.
GB knew victory would confirm a semi-final spot, but faced an uphill task when trailing 3-1 after three ends.
The scores were then tied at 4-4 after eight ends, and while Canada secured one point in the ninth, GB took full advantage of having the hammer in the final end.
And while Canada will be left wondering how their Olympic defence fell apart in the round robin, GB can now look forward to their semi-final.
South Korea and Sweden have also qualified, while one of Japan or the United States will complete the line-up.
