Belarus pulled off one of the greatest shocks in the history of Olympic ice hockey as they beat Sweden's "Dream Team" of National Hockey League stars in the quarter-finals.
Defenceman Vladimir Kopat scored the winning goal with two minutes and 24 seconds remaining.
His shot from beyond the blueline went straight at the face of Swedish netminder Tommy Salo and he could only deflect the puck back into his unguarded net.
Belarus had only one NHL player in Ruslan Salei, but they got the better of their millionnaire opponents.
Salei said: "I think it's unbelievable, absolutely incredible. Nobody gave us a chance."
Sweden are now out of the running for medals in what is being hailed as the greatest Olympic ice hockey upset since the United States beat the Soviet Union in 1980.
Czech Republic 0-1 Russia
A solitary goal from Maxim Afinogenov was enough to book Russia a place in the Olympic men's ice hockey semi-finals.
