EXTRA TIME FOR BRAZIL AND AUSTRALIA

There have been chances at both ends but neither side could break the deadlock in Mineirão so we will have another 30 minutes to decide the last place in the semi-finals.

We're heading for extra time in the women's football quarter-final between Brazil and Australia. It's still 0-0 and we're into added time.

ENNIS-HILL LEADS AT HEPTATHLON HALF-WAY POINT

She says her 200m time was "a bit slow" and she was "devastated" with her shot put display, but defending Olympic champions Jessica Ennis-Hill is in gold medal position after the first four heptathlon events. 

The British athlete enjoys a 72-point lead over nearest challenger Nafissatou Thiam of Belgium, but there's still a long way to go in this one.

TRIPLE DOUBLE ON THE CARDS

Usain Bolt is not the only Jamaican sprinter aiming to make history at the Rio 2016 Olympic Games. Shelly-Ann Fraser-Pryce is aiming for a 'triple double' - as opposed to Bolt's 'triple triple' - by winning gold for the third time in succession at both 100 and 200m. The journey has started well, as she won her 100m heat with the fastest time of the night. Great hair, too.

PHELPS' LAST RACE?

He seems to think so. He described the three-way silver as "kind of special", adding, "It's a decent way to finish my last race. I can't complain too much."

Of course he won't be counting relays in that. We can expect to see Phelps back in the pool for one of those in 24 hours' time.

TRIPLE SILVER: 'THAT'S KIND OF COOL'

Here's something you don't see very often. It's a triple silver medal. Michael Phelps, Chad le Clos and Laszlo Cseh - three swimming greats, three old foes - swam exactly the same time behind Joseph Schooling in the men's 100m butterfly final.

"Well I saw second next to my name and then I looked up again and then I looked over at Laszlo and Chad like, huh, we all tied for second. That's kind of cool," Phelps said.

SCHOOLING: 'I DON'T KNOW WHAT TO BELIEVE'

Joseph Schooling seems more surprised than ecstatic following his momentous win against Michael Phelps in the men's 100m butterfly. It's as if he still needs convincing this isn't all some kind of elaborate joke/dream/alternative universe.

Singapore's first ever gold medallist says, "I'm sorry if I don't seem like I'm full of emotions but I don't know what to believe - that I actually did it or I'm still preparing for my race. I'm between the two of them."

"I need to let this moment sink in, realise what I've done and then I'll have a better understanding of what I accomplished."

Can you blame him? It can't be easy getting your head around becoming a legend in 50 seconds.

TENSE NIGHT FOR MARTA IN MINEIRAO

We haven't even had a chance to mention the football yet, but if you're Brazilian there's a good chance that's the only thing you care about right now. The hosts and Australia are tied 0-0 in the second half of a tense quarter-final clash, with USA's shock defeat earlier opening up the draw.

CARTER DENIES ADAMS IN SHOT PUT

Michelle Carter has clinched the women's shot put gold medal with a huge throw of 20.63 metres, denying New Zealand's Valerie Adams the chance to make history. Reigning Olympic champion Adams was aiming to become the first track and field athlete to win three successive titles in the same event. Carter, on the other hand, had never won an Olympic medal.

ERVIN, 35, WINS GOLD!

Quite the swim, and quite the celebration from the USA's Anthony Ervin, who wins the men's 50m freestyle by a whisker.

He was just one-hundredth of a second faster than silver medallist Florent Manaudou of France. It could not have been closer. What's more, at 35, Ervin is the oldest swimming gold medallist in Olympic Games history.

No wonder he hurls his tattooed torso almost all the way out of the pool in wild elation. 

Now, another swimming final. The men's 50m freestyle is coming right up...

When you win your country's first ever gold and beat Michael Phelps to do it...

BACK TO SCHOOLING...

Winning your country's first ever Olympic gold medal is up there with the best feelings in all sport. But when you beat the greatest ever Olympian Michael Phelps to do it, that's even better. And when you have idolised Phelps since you were a young boy. Well, there are barely any words to describe that are there? 

What a night for Joseph Schooling, who first met Phelps a long time ago...

ADAMS GOES FOR HISTORIC TREBLE

Now let's turn our attention to the first night of athletics action at the Olympic Stadium. It's the women's shot put final, and New Zealand's Valerie Adams Adams is bidding to become the first woman to win the same individual track and field event at three consecutive Olympic Games.

She's on course to do it too. The Kiwi is leading the way after making a season-best throw of 20.42 metres.

KATIE SHOWS HER CLASS

That was a monster of a performance from Katie Ledecky, no one could get remotely close to her. She has smashed the world record and bagged her third gold medal of Rio 2016. She is just 19 years old.

Several seconds behind, Jazz Carlin took silver for Great Britain and Boglarka Kapas bronze for Hungary.
