Team GB equestrian leader Richard Waygood said: "In consultation with Scott, his valued owners and our team vet, we have decided it is in the horse's best interests to withdraw from the competition as a preventative measure to avoid a more serious injury.

"While disappointing for Scott and his connections, the team is still a strong proposition ahead of Friday's team competition.

"Ben and Holly were always going to be in our team line-up, and it is great to bring Harry into the trio at his first Games."

Great Britain's Jason Kenny made it to the quarter-finals via the repechage but was beaten by Dutchman Harrie Lavreysen in the best-of-three battle.

That feels like a big moment.

Carli Lloyd picks up the ball just inside the box and fires a shot off on the angle which creeps past Australia goalkeeper Teagan Micah - that's her ninth Olympic goal - not bad at all.

That caps off a really impressive performance from Lloyd and the USWNT in this first-half.

Carlin pinned Levy up at the top of the track and was utterly dominant in that quarter-final. He was in total control of that race in every moment.

Jack Carlin is looking unstoppable. A ruthless performance from the British medal hope as he leaves Maximilian Levy in the dust and steamrolls his way into the semi-finals.

Up next, Jason Kenny's fellow Brit and tip for a medal...

Jack Carlin won the opening race of his quarter-final tussle.

Great Britain's Jason Kenny goes for broke but Harrie Lavreysen flies past at the finish to progress to the semi-finals.

And this time, Kenny's nine-year reign as Olympic champion is over.

The world champion marches on.

Right, take two for Jason Kenny in the men's individual sprint quarter-final. Lose this and he's out...

You have to have the legs and the lungs and it's judging when there's dangerous moves happening.

We've seen omnium's come down to tight points and everything counts.

Matt is a fantastic young athlete out there.

Viviani wins the elimination race in the omnium but with the points, Walls is stacking them up and he is in the gold medal position!

Elia Viviani takes victory the elimination race from Matt Walls on the final lap but the Great Britain rider is in the gold medal position after three rounds of the men's omnium.

He is four points ahead of Jan-Willem van Schip with one race remaining, Benjamin Thomas is in third.

And now Jan-Willem van Schip is eliminated!

Matt Walls is into the final two against defending Olympic champion Elia Viviani.

I'm feeling the burn just watching this...

Benjamin Thomas goes this time! It's absolutely gruelling. Down to the final four with Great Britain's Matt Walls among them.

Matt Walls has just had to do four sprints consecutively, but he's picking them off one-by-one.

There will be a lot of marathon runners watching this event - it was chosen because it was supposed to be cooler, but still it is tough conditions to walk in at the moment

Six to go. Viviani, Walls, Van Schip and Thomas all still in it...

Corr, it's tight if you're hanging around at the back of the pack. Benjamin Thomas, the world champion, could be in trouble here... the Frenchman looked to have gone but somehow survives!

Matt Walls is leading them round now. Looking strong, the Great Britain rider.

There's a buzzer on each rider's handlebars that flashes up when they're the one who is knocked out for finishing last on each lap. It's all very hectic, like stepping out into the bike lane at Amsterdam Central Station.

We're whittling them down quickly now, but Matt Walls is still in the mix.
