Briton Elise Christie broke down in tears as she again missed out on an Olympic medal after crashing in the 500m short-track speed skating final.
It was the latest setback for the Scot, 27, who was disqualified in each of her three events in Sochi four years ago.
Christie, who was given fourth place, told BBC Sport: "I was knocked over, I didn't fall on my own. I worked so hard. It has been taken away from me."
Italy's Arianna Fontana won gold and Dutchwoman Yara van Kerkhof got silver.
Home favourite Choi Min-jeong, who was beaten to the line by Fontana, was later disqualified, handing bronze to Canada's Kim Boutin.
On the final lap, Christie attempted to move herself into a medal position but fell over in contact with Van Kerkhof.
"Even in the semi-final I got crashed into and ended up in lane four," said an emotional Christie. "It is short track and I am supposed to be prepared for this but it hurts.
"Hopefully I can come back again. I can reset."

Christie's tactics in the previous two rounds were to move to the front early in the race, but in the final she found herself trailing in fourth.
The Scot was briefly in third spot, but as she tried to hold her line on the final lap her hand came in contact with Van Kerkhof's boot which resulted in her careering into wall.
The triple world champion goes again on Saturday in the 1500m and that his followed by her favoured event, the 1,000m, which begins on Tuesday.
'I'm sure she will turn things around'
Sarah Lindsay, a three-time Olympic short-track speed skater, said she was confident Christie would still achieve her goal of winning a medal at these Games.
"I feel terrible for her," she told BBC Sport. "She is skating so well. She will be so disappointed. Elise always said she would risk everything.
"Elise doesn't really have a filter. You always see the real Elise. It's good for people to see how much it really means to her. She is absolutely devastated right now.
"We just have to accept the judges' decision, as hard as it might be. It wasn't down to Elise's own skating. She has to take positives from that - it's not like she hasn't been skating well. There is a lot of expectation on her but she has to put that behind her and move on. I'm sure she will because she is the comeback queen."
'Elise is far more robust than last time'
Stewart Laing, the performance director for British short-track speed skating, said the team's sports psychologist will help Christie "cope" with the disappointment.
After Sochi, Christie suffered online abuse and death threats following a collision with South Korean skater Park Seung-hi.
Laing told BBC Sport: "Hugely disappointed but that is the nature of short track. Unfortunately she finishes in that soul-destroying fourth place.
"We have brought our sports psychologist out and we have had this planned just in case. We will regroup and refocus. We will give her time to digest but then help her cope with what's happened.
"Crucially Elise is in a much stronger place. She is far more robust than last time. She has actually finished the race so it's different to Sochi. Obviously none of us wanted it to be written this way but we come back on Saturday in her best event."
'Attack this pain head on'
There were words of encouragement for Christie from team-mates and other British Olympians.
How the other Brits fared
In the men's short track, Farrell Treacy, who crashed out of the 1500m heats, reached Saturday's quarter-finals of the 1,000m after finishing second in his heat. However, Nottingham's Joshua Cheetham failed to qualify for the next round after finishing third in his heat.
And Scot Andrew Young was 46th in the cross-country sprint classic.
