Earlier on, Fiji's Jerry Tuwai showed his twinkle toes to score. Fiji send New Zealand out of the Olympics and to their third defeat of a disappointing tournament. Fiji march into the semi finals.

James Davies went from Red Rum to Bambi there when it mattered. Ten metres shy.

So close to another British medalpublished at 22:14 British Summer Time 10 August 2016

Gymnastics: Men's all-around final

Great Britain's Max Whitlock could well be celebrating an Olympic medal in the next 30 minutes.

With one piece of apparatus left in the men's all-around final, he is third, with only his floor routine to come, after an effort of 14.700 on the high bar. It is so close though, he can not afford any mistakes to stay in the top three.

Ukraine's Oleg Verniaiev, the European champion last year, has one hand on the gold after a huge score of 16.100, the highest from any gymnast on any apparatus in this final, on the parallel bars. Japan's Kohei Uchimura, the reigning Olympic champion, is still second.

A thrilling break from James Davies as he hands off two Argentines and streaks for the corner, is this the killer try...No! Tackled within sight of the line...

GB five minutes away from a semi-final, maybe one mistake away from defeat. The tightest game of sevens I've seen so far. Still scoreless...

GB have got the wind behind them in the second half so they can play a territory game. 

Tactically they have played it very, very, well. They are two evenly matched sides

It's hammering down at Deodoro Stadium. The ball is slippy and the pitch cutting a little in parts.

No cover for any spectator in the house so it's get wet and enjoy it.

James Davies take a bow. What a magnificent turnover.

That was a try-saving bit of work.

Great Britain's Rebekah Tiler finished tenth in the women's -69kg weightlifting earlier today, but she is relishing her Olympic experience.

"I'm going to get in the pool, meet a lot of other athletes and get a load of selfies. I want to get one with Usain Bolt - I've been trying for ages," she said.

"I've been on a diet so now I can chill out and eat pizzas and brownies and stuff - all the nice food.

"This Olympics is all about experience and getting used to that kind of environment

"It was just an amazing experience, just getting on that platform with everyone screaming your name."

Some superb defending from James Davies prevents a score bang on half-time, and it's scoreless at the interval.

Discipline will be key tonight. In every game of sevens I've seen, a yellow card and a sin binning usually means defeat.

Captain Tom Mitchell has to scurry back 50 yards to cover a testing kick, and he does it brilliantly. 

Not the biggest crowd in but it's plenty noisy enough. You won't find a quiet Argentine in Rio this month. Maybe ever.

As expected the wind and rain making life tough, a few early handling errors from both sides.

Under way! GB captain Tom Mitchell could hardly contain his delight when he ran out on to the pitch. Clive Woodward in the comms box says GB will match the power of their opponents but the weather could be a big factor...

Here we go then. The players are out. Great Britain in red, Argentina in their usual sky blue and white hoops. Big support for the South Americans in the Rio night.

It's not all good news for Fiji, though. Their football team have lost 10-0 to Germany, who progress to the quarter-finals as a result.

It was a particularly good day for Nils Petersen as the SC Freiburg scored five goals.

Germany play Portugal on Saturday.

Japan are also through to the last four after beating France 12-7. The last quarter-final will be Australia v South Africa, which is after this GB-Argentina clash...

The rain falls down on the Deodoro Stadium, it's a miserable old evening. A place against either South Africa or Australia in the semis awaits though.

Keep it in hand? Could be a challenge...

Watch GB here. 

Earlier on, Fiji beat the USA to ensure that new Zealand reached the last eight of the rugby sevens by a single point. Their prize? A tie against New Zealand. The Fijians, though, made it through 12-7, despite this try from Gillies Kaka. GB up next...
