Incredible drama in the long jump as American Jarrion Lawson thinks he has won gold, but clipped the sand with his left hand, to leave him in fourth overall.

The great David Rudisha - who broke the 800m world record in London - wins the third and final semi in a time of 1:43.89.

Are we still awake! What an hour of sport. Still more to come. 

A hugely emotional Mo Farah breaks down in tears in his BBC interview. What a man!

Football, you're taking a very back seat but you can have your 15 seconds of fame here.

Take a look at Neymar putting Brazil in the lead.

Mo Farah had to work hard but what a run! 

In the final 100m he was under serious pressure from Paul Tanui of Kenya, but with a kick and a sprint he crosses the line first and wins gold.

Mo Farah makes history and becomes the first British athlete to win three Olympic gold medals on the track.

Greg Rutherford might have lost his Olympic title, but in one of the great long jump finals - in terms of drama if not distance - he proved his immense championship character with that last-round leap. Just two centimetres down on the jump that won his gold in London. He will be hurting now, but there will be satisfaction to follow.

No pressure but how would you ever even get over something like this?

This may not be Super Saturday but it is Special Saturday. Athletics needed a night like this.

Fran Halsall after coming fourth in the 50m freestyle: "I thought I was in really good shape and it was a season's best.

"I could not have asked for anything more. It hurts not to get a medal. I did my best but it wasn't enough unfortunately."

Heartbreak for Fran Halsall as Pernille Blume of Denmark takes gold, Simone Manuel silver and Aliaksandra Herasimenia bronze for Belarus in 50m final.

Gold for Farah, Ennis-Hill in silver, Rutherford with a brilliant last-round effort to nick the bronze. It might not be Super Saturday II, but it's many other things - Stressful Saturday, Sick Feeling in Stomach Saturday, Sugar He's Fallen Over Saturday...

That looks conclusive. His left palm is in the sand behind his head. Jarrion Lawson misses out on a medal and we shall never know how far that jump could have been!

This has turned into one of the greatest long jump events ever. Maybe not in terms of distance, but in terms of who wins what.

Wow! Jarrion Lawson seemed to have nailed a huge jump to push Greg Rutherford out of the medals but it's only measured at 7.78m!

He can't believe it, his coach is going mad but it looks like his trailing hand touched into the sand behind his head!

A schoolboy error. Lawson is livid. 

Jarrion Lawson up last. He's now down in fourth...
