"The start of the men's biathlon 15km mass start event at Laura biathlon course on Sunday has been delayed by one hour due to cloud and fog. The new start time is 20:00 (16:00 GMT).

"That means Ole Einar Bjoerndalen will have to wait as he bids to become the most decorated Winter Olympian, if he gets another medal to take him up to 13."

Shoot-out alert - They might have edged it 36 shots to 27 but Russia have failed to get on the scoreboard in 65 minutes against Slovakia, and it comes down to a shoot-out, 24 hours after they lost to the USA in similar circumstances. Three players have already been nominated for each side.

Slovenia score late on and the United States goaltender Ryan Miller looks furious with himself as he allows Marcel Rodman's shot past him.

But it is still little consolation for Slovenia, who have had a day to forget. The United States notched up 28 shots and scored five times to continue their run of success. By contrast, the Slovenians had 18 shots but were wasteful.

Jorien Ter Mors of the Netherlands has set a new Olympic record of 1:53.51 in the women's 1500m, beating Olga Fatukina's time by a massive 4.37 seconds.

Ter Mors is also a superb short-track skater and was fourth in Saturday's 1500m final.

Overtime alert - despite battering away at the Slovakia goal in the third period, hitting the post twice and the bar, Russia cannot make the breakthrough and, for the second day running, are taken to a five-minute extra period of four v four (one player is removed from each team) golden goal drama. Beyond that, a shoot-out looms.

"That was some skate by Olga Fatkulina. The coaches of Wust and the other competitors will be watching this time closely. Her legs nearly gave out late on and she spluttered a bit in the finishing straight, but that was impressive."

Adrian Alara, external: "This Ice Hockey match is epic! Could go either way."

Nicola Nanev:, external "I am sure Russia will get away with the win here. I just hope this does not go to penalties."

This is too easy for the Americans. A fifth goal goes in, this time from forward David Backes, who is known on the NHL circuit as "Inglorious" Backes after he was involved in three separate fights in a single season. Slovenia are keeping up with the Americans in terms of shots in the third period, trailing by just four shots to six, but they cannot find the target.

Russian Olga Fatkulina is the new leader at the Adler Arena after storming into the lead with around a third of the competition gone. Fatkulina, who was the silver medallist in the 500m, finished in a time of 1:57.88, beating Belgium's Jelena Peeters's time by 1.85 seconds.

Norway's Magnus Moan,, external who has two Winter Olympic medals in the Nordic combined, has posted videos of his training routine on Instagram. One sees him jump head first, external down the side of a mountain, while in the other he is captured in the gym recreating , externalthe famous old Dirty Dancing dance routine, taking on the Jennifer Grey role rather than Patrick Swayze's as he is lifted into the air by some burly chap.

You can watch Moan having the time of his life in the individual Gundersen large hill 10 km, external on Tuesday. No-one will be putting him in the corner.

Russia are piling on the pressure as they look to break the deadlock in their final Group A match and Slovakia only survive when a shot hits both the crossbar and post, but doesn't cross the line, much to the disappointment of the increasingly desperate crowd at the Bolshoy Ice Dome. The complicated qualification scenario sees all three group winners and the best-placed second team progress to the quarter-finals, with the remaining eight teams playing off for the other four quarter-final places.

Belgium's Jelena Peeters is currently the woman to beat with a time of 1:59.73 but that is all likely to change. Favourite Ireen Wust's biggest rival is her compatriot and rising star, Lotte van Beek, who beat her in the season's opening 1500m World Cup race in Calgary. The 22-year-old, appearing at her first Games, will race in the 18th and last pair so it promises to be a nerve-jangling end to this competition.

Those of you unfamiliar with the world of speed skating may not know that skaters compete in pairs and rather than race directly against each other they compete against the clock, with the highest-ranked skaters racing at the end of the competition. If you ever find yourself chatting about speed skating in the pub (it might happen) then perhaps throw this into conversation: The first Winter Olympic gold medal was won in speed skating in 1924 and is one of a handful of sports to have featured at every Winter Olympics.

The women's 1500m has just started at the Adler Arena and reigning Olympic champion Ireen Wust of the Netherlands is the favourite to retain her title and add to the 3000m gold and 1000m silver she has already won in Sochi. Wust, who won the world title last year and is bidding for a fourth career gold, is paired 15th.

Joanne Lifford, external on Twitter: "I'm surprised they don't break lots of sticks in ice hockey. What are they made from?"

Patch, external on Twitter: "Yevgeni Malkin, external is the best player on the ice today but Russia are leaving him out to dry too much."

Rob Howe, external on Twitter: "I just get a feeling Slovakia are going to nick a goal here...."

Another 20 minutes pass by with Russia unable to break down the Slovakia defence, and indeed it is the visitors who are pushing harder with 13 shots to 11 in the second period.

It goes from bad to worse for Slovenia. A third goal from Phil Kessel and a goal from defender Ryan McDonagh sees the favourites double their advantage and at 4-0 the Americans are comfortable.

The men's cross-country participants were given the honour of a morale-boosting visit by Russian President Vladimir Putin earlier today, as he joined Sports Minister Vitaly Mutko and Prime Minister Dmitry Medvedev on a trip to the Laura Cross-Country Centre. Hopefully no-one mentioned the ice hockey.
