Norway's Maiken Caspersen Falla won her maiden Winter Olympic title when she won the cross-country sprint event after compatriot, defending champion and hot favourite Marit Bjoergen crashed out in the semi-finals.
Bjoergen, who won the individual sprint in Vancouver four years ago, was seeking her fifth Olympic title but failed to make the final where Falla was never threatened.
Team mate Ingvild Flugstad Oestberg produced a late surge to catch Slovenian Vesna Fabjan on the line and take silver by two hundredths of a second.
