The Finns and Czechs seemed destined to go to overtime tied at 0 until Niklas Hagman scored on the flukiest of goals with 6:26 left in the third period.
Czech defenseman Pavel Kubina ventured behind his own net to retrieve his helmet, while Hagman simultaneously fired between the legs of Tomas Vokoun. After grabbing his helmet, Kubina looked up to see the puck in his own net.
Valtteri Filppula later scored into an empty net, sending the Suomi, including Ducks teammates Teemu Selanne and Saku Koivu, into the semifinals. They’ll play the United States on Friday at noon.
