Three of the Austrian team have got out of the sled and the medical team are on hand.

Oh yes! Men's silver medallist Noe Roth pulls out a huge jump at crunch time once again!

Back double full-double full-full for 129.54 points (he scored 127.50 in his first-round jump).

Switzerland move onto 296.91 points. Surely they can't sneak silver here?

Anxious moments as the Austrian sled crashes early in their second run.

We're just over an hour into the men's 50km start, passing through the 27km checkpoint, and it looks like it's going to be a Norway 1-2-3.

Martin Loewstroem Nyenget, Johannes Hoesflot Klaebo, and Emil Iversen come through in that order and they've distanced Savelii Korostelev and Victor Lavera - the Frenchman looks like he's going backwards!

Norway's trio are over one minute clear.

GB's Andrew Musgrave is in eighth place, trailing by 1:52.1.

A big squat from Connor Curran but he saves the landing. Back full-double full-full and into the arms of his team-mates, who are delighted. 113.72 points for Curran.

Is it going to be back-to-back Olympic titles for USA?

As it stands with one round of jumps to go:

1. USA - 208.16
2. China - 184.31
3. Switzerland - 167.37
4. Australia - 160.16

Men's individual gold medallist Wing Xindi does not land cleanly, ending up forward rolling down the slope. Great gymnastic ability but obviously not what the judges are looking for.

It's a score of 87.72 for him and an overall score of 184.31 for China.

You feel this is USA's gold to lose now.

British interest in the ski cross lies with Ollie Davies who goes in heat three of eight with the top two in each four-man heat to qualify for the last 16

We'll keep you up to date on how he fares.

A huge 123.00 from Pirmin Werner! And with Australia's Danielle Scott not landing perfectly (95.30), Switzerland stay above them in the standings. They're firmly back in the medal race.

It's started to snow in Livigno.

Not for the faint-hearted, ski cross features a frenetic race to the finish line on a course littered with jumps and obstacles.

For the knockout stage, the top seeds are placed at opposite ends of the draw for the knockout stage, while the highest-ranked skier in each race gets to choose their starting gate.

The competition continues with four skiers per race. The top two in each race qualify for the next round. Up to and including the semi-finals, any ties are settled in favour of the athlete with the better seeding – as denoted by bib number.

The four successful semi-finalists compete for the medals in the ‘big final’. Any athletes who can’t be separated by a photo finish (first body part across the line) will be awarded the same colour medal.

Hello Sian - we think death cookies refers to the lumps of hard-packed ice and snow on the surface or just under it. If you land on that, good luck staying upright.

For heat two of the men's four-man bobsleigh, the 25 top-ranked sleds from heat one start in reverse order, followed by the remaining sleds (from 26 onwards), where more than 25 sleds are entered.

That means that the GB sled of Brad Hall, Greg Cackett, Leon Greenwood and Taylor Lawrence will start 23nd with only the two German sleds piloted by Johannes Lochner and Francisco Friedrich to come after them

The third and fourth heats will take place on Sunday.

A solid jump from USA's Kaila Kuhn. She lands nicely - big squat before slamming her legs together, arms outstretched to the side - but there's a gap between her knees in her final somersault. She scores 94.44.

As it stands after run one:

1. China - 96.59
2. USA - 94.44
3. Australia - 64.86
4. Switzerland - 44.37

Women's individual gold medallist Xu Mengtao (China) is the first athlete to land a jump in this final. She's pretty chuffed but her score of 96.59 probably isn't as high as she'd been hoping for.

Andrew Musgrave's medal hopes in the men's 50km appear to be over - he's more than 30 seconds off the pace (which, of course, is being set by the Norwegians).

A group of five - three Norwegians, one neutral athlete and one French - got away midway through lap three and Musgrave didn't receive much support in his attempt to chase them down.

Switzerland kick off this final but Lina Kozomara can't stick her landing - she gets caught in the "death cookies". She scores 44.37.

However, Abbey Willcox (64.86) also tumbles on Australia's opening jump.

Switzerland are still in this!

We're under way in the mixed team aerials final in Livigno where a gold medal is up for grabs.

Four teams of three skiers, one jump per athlete, highest combined score wins.

Here's a reminder of how they fared in qualifying, but remember, the scores are reset for the final so none of that matters now!

1. USA - 351.23 points
2. China - 315.02
3. Australia - 289.04
4. Switzerland - 278.48

This is a critical part of the race - Musgrave, who's leading the chasing pack, has to get back across to the leaders soon otherwise it will be a struggle.

Finland's Iivo Niskanen (the 2018 champion), who has been struggling with illness, grinds to a halt and exits the track on the third lap. He'd shown himself at the front of the race a couple of times in the opening couple of laps.

A Norwegian - Harald Oestberg Amundsen - has also dropped out but his compatriots Emil Iversen, Martin Loewstroem Nyenget, and Johannes Hoesflot Klaebo remain at the front.

They're part of a breakaway group of five with Savelii Korostelev (neutral athlete) and Victor Lovera (France).

GB's Andrew Musgrave leads the chasing pack.

We should mention that Great Britain's Joe Davies is going really well here. What an effort.

He's never done a 50km race at this level.
