19:12Not only are Kyle Evans and Liam Phillips going in the BMX seeding races, but there is also British interest in the women's 10m platform qualifying. Tonia Couch and Sara Barrow are looking to progress with Barrow lying fifth after one dive and Couch ninth.

BBC Sport in RioA plus side for Edzus Treimanis - he probably won't have to do any media given he crash landed so far away. Every cloud.

BBC Sport in RioWe have our first wipeout. Latvia's Edzus Treimanis made it about 50ft from the ramp and then landed hard on the back wheel. Big air. Too big.
A cracking "ooohhh" from the crowd. He looks lost, then thinks his best tactic is to wave and just accept that he briefly looks like a bit of a plonker.
No need for that ambulance I showed you earlier thankfully. Old Edzus is right as rain. Well, physically at least.

Six-time Olympic cycling champion on BBC OneThat is the worst place to crash. At least he is up on his feet but it didn't look good.
It is not the ideal way to start your Olympic campaign.

19:04The first crash! Latvia's Edzus Treimanis stacks it and whacks his head on the floor. The helmet saves him a nasty injury, but there's still claret coming from his forehead.

No racing before 19:15. By that time the boats will have been out there for more than an hour. It's like watching a still life painting.

BBC Sport in RioThat's a fairly clean run for Kyle Evans. He looked to take corners smoothly and sixth is no disaster thus far.
The Wigan-born rider could slide a bit though as riders come out according to their world ranking, so the best are yet to come.

Mark Costello: Why do some BMX riders look like they are doing tricks when in the air? Wouldn't that slow them down?!

It is good to get your first ride out and get rid of the nerves.

18:5935.776 seconds for the Briton. That's the sixth-fastest time so far, with more than half of the 32-man field to go. This just determines the seedings, remember.

BBC Sport in RioThere's a superb atmosphere at Radical Park for the BMX now despite the venue being around 40% full by my estimation.
The flags appear from all angles as Brazilian Renato Rezende finishes third fastest of the male riders so far. There will be 32 competitors in all.
Before each rider goes there's a moment of silence where the tannoy takes over and as soon as the gate goes down and the ramp is descended, the music blares out. Feel the noise.

The rout is complete. Neymar scores his second, this time an injury-time penalty, to give Brazil a sixth.
In their last semi-final on home soil, Brazil lost 7-1. Now they are going to win 6-0. 7-7 on aggregate.

18:45Men's semi-final: Brazil 5-0 Honduras (79 minutes)
It is 5-0 for Brazil in their semi-final against Honduras. Luan taps into an open goal from close range after a fine run from substitute Felipe Anderson.
Ten minutes to go. Brazil are definitely in the Olympic final. Germany and Nigeria play each other for the right to join them later on tonight.
