Danny Barrett opened proceedings for the USA.

Talk about schoolboy bullies, if it was going to be someone it was him.

He's big, he's bold, he's brash and he's quality to watch.

Hard as nails.

Danny Barrett, a massive lumberjack of a man, stampedes past Ethan Waddleton to score the first try of the quarter-final.

Perry Baker skips in for two quickfire tries and Great Britain are reeling at 21-0 down with still two minutes of the first half to go.

Tom Mitchell is off injured as well. Tough trench to get out of here.

They've played the USA in the build-up to the Games so they know what to expect.

Tom Dean's sister Connie has been talking to BBC Radio 5 Live about her brother becoming Olympic champion.

"I've always known he could do it and we've spoken about this since he were about six or seven," she said.

"We used to talk about it when we were kids and we used to pretend that we'd won the medals.

"I can't believe he did it!"

New Zealand have just put away Canada in the first of the men's sevens quarter-finals.

They will play the winners of the next match in the last four.

Great Britain, silver medallists in Rio, or the United States.

The teams are due on the pitch shortly,

Well then!

Liam Broady rushes to the net and, with the slightest of forehand volleys, dinks the ball back over to break Hubert Hurkacz in the deciding set.

But this is not what you want to see in the ring.

Moroccan boxer Youness Baalla bit opponent David Nyika of New Zealand during their round of 16 tie.

And Caroline Dubois eased through to the next round of the women's lightweight division with victory against Kosovo's Donjeta Sadiku.

Here's the best of that bout.

Team GB's Pat McCormack began his bid for gold by beating Belarusian Aliaksandr Radzionau in the men's welterweight round of 16.

GB have picked a team here with no forwards.

They are playing a fast game, not necessarily an attacking one.

Great Britain face the USA in the rugby sevens at 10am.

The USA are still struggling against Australia, who came closest in the first half when Mary Fowler's header hit the crossbar. It's still 0-0 at half time.

Sweden remain in fine form and are currently top of the group as they go in at the break 2-0 up over New Zealand.

Liam Broady saves a couple of set points but a Hubert Hurkacz ace ensures that this match is going to a third and final set.

Broady's opening match also went three, with the Brit gritting his way through a three hour tussle.

Can he do it again?

One of the remarkable things is that it's a partnership. It's thrilling when you have a horse for the first time and you try and teach it something new and it remembers. You feel such joy like a parent.

The horses are incredibly intuitive, I get very emotional watching the dressage because I feel the pride people have in their partnerships. It's dreamy. You cannot force the animal to do things. If it doesn't get on with you, it won't happen. It's a synergy and it's magical.

Team GB, consisting of Carl Hester on En Vogue, Charlotte Fry on Everdale and Charlotte Dujardin on Gio are yet to get started in the team dressage final, where the Netherlands' Marlies van Baalen's has posted the top score so far in the early stages.

First up for GB will be Carl Hester at 10:00 BST.
