Great Britain's men's curling Winter Olympics medal hopes have been cast into doubt after a shock 8-6 defeat by Norway left them scrambling to make the semi-finals in Cortina. Bruce Mouat's world champions had lost two of their opening six matches, but were expected to beat the Norwegians for their fifth victory of the competition. But a few untimely errors, combined with a disciplined display by their unheralded opponents, left them 6-4 down with two ends left. "We need to win our next two to make sure we're definitely in the semis," lead Hammy McMillan told BBC Sport. "We're doing a lot of the right things, we just need to find that extra inch."
