American 2016 world silver medallist Ashley Wagner is full of sympathy for Russian favourite Kamila Valieva, who suffered a error-strewn performance in the free skate, and fell short of the podium.

Ben Heath: I’ve subtly stopped listening to my lecture to keep a track of the curling.

That's another poor shot, that's two in a row from Chris Plys. They need to score, and score well in this end.

A shake of the head from John Shuster and that is the first time I have seen him look non-plussed in this match.

The Americans are suddenly a lot quieter. They're in a spot of bother here, but John Shuster often gets them out of sticky situations.

USA skip John Shuster seems to have have no internal monologue.

Every thought process about the possible plays for his team is vocalised. I am not sure if it is for the benefit of his team or himself.

Chris Plys has had a couple of ropey stones for the United States. The door is ajar for Great Britain.

Bruce Mouat calls for a time-out and coach Murdoch comes down to the ice to advise over what Great Britain can do...

Laura Alice: The fact that the BBC Olympics commentators are literally in tears about this Figure Skating final says it all. 15-year-old child.

Figure skater Polina Edmunds, who represented the United States at Sochi 2014, says that a suspension for Kamila Valieva would have saved her a intolerable situation.

Valieva has her hands on her hips as she leaves the ice, while a section of the crowd with ROC flags shouts "well done" in Russian.

Don't go anywhere - this is all going to explode sometime soon.

Oh boy, it's tense.

Another blank means GB will have the hammer in the last end as it stands. But the US could opt to try and blank the end again.

It could prove pivotal either way.

It's still 3-3 in the other match between Sweden and Canada, too.

This has got very tactical.

John Shuster opts to blank the eighth end and keep the hammer rather than take a one and give Great Britain last-stone advantage.

It is all boiling up into a humdinging ending.

Alexandra Trusova of the Russian Olympic Committee finishes with silver. Japan's Kaori Sakamoto takes the bronze.

One of the most uncomfortable, unpleasant periods of sport you will see.

She looks utterly distraught.

There is something of a stunned silence in the area.

Slightly speechless - for all the wrong reasons.

Kamila Valieva looks distraught as she waits for the judges' scores. Her coach has an arm around her.

She finishes in fourth after a string of mistakes.

Stunned silence in the area.

You can't help but feel that she shouldn't be out there at all, not least of which for the failed drug test reasons. But she is a 15 year old child.

Gasps as Valieva makes mistakes on four jumps ... she has never done that in this routine before. The applause is sympathetic more than anything else.

Valieva breaks into tears seconds after her routine ends.

That will not be good enough to top the standings. A horrible few days for sport ends with more tears.
