Hammy McMillan and Bruce Mouat of Team GB face an early exit from the Winter Olympics after defeat by Canada

Team GB's Winter Olympics curling medal hopes are now in serious jeopardy after Bruce Mouat's world champions were beaten 9-5 by Canada in Cortina.

Arriving in Italy as gold-medal favourites, the British quartet have lost four of their eight matches in a round-robin stage full of maybes and might have beens.

Now, they must beat the United States in their final game on Wednesday (13:05 GMT) and hope other results fall in their favour if they are to reach Thursday's semi-finals and salvage their chances of a podium place.

The 2022 silver medallists have spoken all week of playing well, but coming out on the wrong side of the narrow margins. And that was the case again against their great rivals high in the Dolomites.
