12:23am - Gymnastics: USA Gymnastics says Biles withdrew with a "medical issue" that will be reassessed over coming days to determine whether she can contest the all-round and apparatus finals later in the week.
Biles is the only gymnast to qualify in all four apparatus finals.
Midnight - Swimming: Another seven swimmers beat Reid's time in heat four, so he is officially out of final contention, as the final heat gets underway. That concludes the Kiwis in competition today, but we'll stick around to keep an eye on the developing situation at the gymnastics...
11:56pm - Swimming: Three swimmers in heat three beat Reid's time, so he is already ranked fifth with two more heats to come - the seeded races.
11:47pm - Gymnastics: Meanwhile, in a developing story, American superstar Simone Biles has withdrawn from the team event, after she appeared to injury a foot during the vault.
11:38pm - Swimming: Reid wins his heat in 7m 53.06s, so four seconds slower than Johansson. That probably won't be enough to see him through, but maybe he would have gone faster in a faster heat.
Let's see where that lands him...
11:36pm - Swimming: Reid still leads at 600m, but this is slower than the first heat.
He's drawing away now and will need to finish fast. With 100m left, he will need a 55s final stretch to beat the previous winner.
11:32pm - Swimming: Kalmar from Hungary takes the lead off Reid at 200m, but the Kiwi is still second at 250m.
Not much between them at 300m, but Nguyen of Vietnam is right with Reid now and passes him over the next 50m.
Halfway through and only 0.31 seconds over the first three, with Reid third.
Reid retakes the lead over the next length and still there at 500m, although Markos from Greece is on the scene now.
11:29pm - Swimming: Johansson of Weden has taken out the first heat in 7m 49.14s, so Reid will need a personal best to beat that.
Reid actually leads over the opening 50m, but obviously early days yet. He leads at 100m in 57.23s and 150m too.
11:21pm - Swimming: Nearing the final Kiwi to perform tonight, with Zac Reid contesting 800m freestyle heats at the Tokyo Aquatics Centre.
Reid is in lane six of the second heat, with a best time of 7m 53.50s - three others in his heat have swum faster, with five heats on the programme and the fastest eight progressing to the final.
9:53pm - Sevens: Huge upset, with Argentina - one man down for most of the game - have held on to beat South Africa 19-14 in their quarter-final, booking a semi spot against either Fiji or Australia.
9:51pm - Football: The Football Ferns have held Sweden scoreless over the second half of their Pool G match for a 2-0 loss - that's the first half they haven't conceded a goal this tournament.
Regardless, NZ are now out of the tournament and that's the end of coach Tom Sermanni's stint with the programme.
9:45pm - Sevens: Meanwhile, Argentina lead South Africa 14-67 early in the second half - despite having a player red-carded in the first. This could be a huge boilover.
9:42pm - Football: Ferns striker Hannah Wilkinson is substituted out of her 100th game for NZ, replaced by Gabi Rennie, who scored against Australia on debut last week. Only a few minutes to go, with Sweden leading 2-0.
9:23pm - Football: Halfway through the second half, NZ have held Sweden scoreless since the break and were unlucky not to have a penalty awarded, after the keeper brought Ria Percival down in the area. Referee and video review unsighted.
9:22pm - Sevens: And the Brits have staged a huge comeback to overhaul the Americans 26-21 in their quarter-final and book a semi against the All Blacks Sevens tomorrow - 19 unanswered points in the second half.
9:11pm - Sevens: At halftime, USA lead Great Britain 21-7, so looks like NZ will face the Americans tomorrow at this stage.
8:57pm - Sailing: Out on the water, Burling and Tuke have got their 49er title defence off to a mediocre start, finishing 12th in the opening race. Weather conditions have not been conducive to sailing off Enoshima and their two other scheduled races have been postponed.
8:54pm - Football: Meanwhile, the Football Ferns have reached halftime only 2-0 behind Sweden, with goals to Anvegard and Janogy.
8:51pm - Sevens: TRY to Jones
With time up on the clock, Canada have one last chance to salvage some respectability and Jones skids over in a couple of tackles. Too late, NZ 21-10
They will now face Great Briatin or USA in the semis tomorrow, whoever win the next quarter-final.
8:47pm - Sevens: TRY to Kay
Canada are over the line, but called back for a forward pass. They're playing under advantage though and from the penalty, they put a kick through, which Kay gathers to score under pressure from Newstubb, NZ 21-5
8:45pm - Sevens: NZ slowing the game down, happy they have a comfortable lead with four minutes remaining.They win another to thwart another Canada opportunity.
8:42pm - Sevens: Canada try to hit back from the restart, but a big tackle on the tryline ends their hopes for now, as NZ can clear their line.
8:41pm - Football: Quick update from the Football Ferns, who still trail Sweden 2-0 nearing halftime.
8:38pm - Sevens: TRY to Curry
With time up in the first half, Canada try to mount an attack, but concede a penalty. NZ have one last chance to stretch their advantage. Mikkelson pops the ball to Curry, who sprints 50m to score his second, NZ 21-0
8:36pm - Sevens: TRY to Curry
Another promising attack ends when a pass goes astray, but NZ win the counter-ruck and Curry adds the second try, NZ 14-0
8:35pm - Sevens: TRY to Newstubb
From a penalty near the tryline, NZ take a quick tap and Newstubb takes the gap to open the scoring, NZ 7-0
8:34pm - Sevens: Canada turn the ball over near their own line, but great defence from NZ pins them deep and eventually wins an attacking scrum.
8:33pm - Sevens: Canada win the kick off, but NZ eventually gain possession through a breakdown penalty. What can they produce?
8:29pm - Football: As NZ and Canada take the field at the sevens, Sweden put their second goal on the Football Ferns and the rout is on!
8:26pm - Sevens: Canada were the lowest qualifers for the quarters, finishing as one of the best third placegetters in their pool.
The All Blacks Sevens lost in the quarter-finals at Rio 2016, falling to eventual champions Fiji, after losing to Japan and Great Britain in pool play - a forgettable result for the NZ men.
8:22pm - Sevens: Only moments away from NZ's mens quarterfinal against Canada, the first of the four medal matches tonight. Later, Great Britain face USA, South Africa take on Argentina and champions Fiji play Australia.
Women's football: New Zealand - 0 Sweden - 1

Here's NZ's starting line-up.
KAYAK SLALOM: Kiwi Luuka Jones finishes sixth in final.
Last but definitely not least, here comes Aussie juggernaut Jessica Fox.

Tauranga's finest is underway! Strong start, through the early gates quickly. Hesitant through gate six.
Two seconds off the leading pace through gate 16 of 25.
Tricky through the back stream, working hard through the final gates.
Jones' time is 110.67. She's in the bronze medal position with four paddlers to come, including hot favourite Aussie Jessica Fox.
Great Britain's Kimberley Woods into the mix now. Early gate miss from the Brit, that will cost her. Four penalties incurred, she's well out of the running.
Jones up next!
Here comes defending Olympic champion Maialen Chourraut from Spain.
On pace with the leading time here through the middle stages. Stumbles a bit in the final gates, but it's still good enough to claim the provisional top spot.
106.63 is now the time to beat. Woods up next, then Luuka Jones.
Netherlands' Martina Wegman next up. Well off the pace here, finishes at 111.33. Seven paddlers to go, Jones just two back in the queue now.
Ukraine's Us up next. Slow start from which she never really recovers, think we can rule her out of medal contention.
Finishes with a time of 111.85.
Poland's Zwolinska is the first out of the blocks for the final. She cops an early penalty on gate four, but clocks a time of 106.98 to set the early standard.

Jones has officially qualified fifth for the final, which begins at 7pm.
Germany's Ricarda Funk bumps Jones down to fourth fastest.
Here we go, Jones out the gate!
Great speed out of the blocks. Negotiates the first two gates well, stumbles on the third but recovers well.
Two second penalty, takes a more cautious approach through the last of the upstream gates.
Over the line she goes, and Jones has qualified third fastest for the final with a strong time of 108.97.
Italy's Stefanie Horn is underway. Jones is up next.
Meanhwile, Peter Burling and Blair Tuke are awaiting the first of three races today, as they attempt to defend their Olympics 49er title. Lack of wind has caused a delayed start.
Slovakia's Eliska Mintalova at the top of the table. Jones has four competitors ahead of her in the queue, should be in the water in the next 15 minutes.
The top 10 competitors from this semi-final will advance to the final.
Jones is preparing to take to the gates for her bid for the final.
Sam Meech has finished 16th in race four of the men's Laser. He's currently placed 19th overall.
Plenty of Kiwis underway in the sailing.
Forgettable start for Rio 2016 silver medallists Alex Maloney and Molly Meech, who capsized in the 49er FX class in their opening race, then were disqualifed in their second race, after mistiming their run at the start line.
They'll have plenty to time to make up in race three, which starts at 4:50pm.
HOCKEY: Black Sticks Men - 2 Japan - 2
It's all over in the hockey, as the Black Sticks Men have to settle for a 2-2 draw against a determined Japan outfit.

Absolute shutout for the Kiwi, who reaffirms his medal potential with a superb debut fight.

Nyika getting loose now, mixing in some uppercuts, as he extends his combinations. Baalla lands a body shot, Nyika counters over the top with the right.
Nyika measures the left hook, punctuated by the ever-present jab. Doubles up and brings the left straight behind it.
And we are done here, Nyika far too classy. Looks like Baalla may have attampted to pull a Tyson v Holyfield with a bite?
Crisp one-two to open the round for Nyika. The Kiwi showing his class, his hand speed is causing Baalla all sorts of issues.
Nyika wears a left hook, best punch of the fight from Baalla. But Nyika just keeps racking up the jabs, using his range to stay clear of any counters.
Baalla's defence being breached at will by Nyika's jab, another comfortable round in the bag for the Kiwi.
They touch gloves and we are into the action.

Nyika jumps into the ring, wearing Blue to Balla's red.
We are going to switch to the boxing ring now, where Kiwi Nyika is set to make his Olympics debut in the heavyweight division.

NZ refer a deflection in the circle and are awarded a penalty corner. Deflection out of bounds, they'll have another crack.
Bang, second time lucky and the Kiwis have equalised through Sam Lane. Big deflection gives the keeper no chance.
8 mins - GOAL JAPAN
Wow, that was special. Kenta dribbles from halfway, breaks off two defenders then slides one past the NZ keeper. That's the best hockey play I've ever seen, and I have seen very few.

Ouch, painful start to the second half, as the Japanese defender cops a hockey ball right on the kneecap. He'll be feeling that in the onsen later.
Second half underway
Anyone's game here after a back and forth first half, although you'd have to say the Japanese have created the most chances.
Goal mouth scramble results in a penalty corner for NZ.
Sloppy execution from the Kiwis, Russell unable to get off a clean shot and ball rolls to safety.
It's a real midfield tussle out here, scoring opportunties have been scarce.
Penalty corner goes NZ's way. Shot from Russell deflects off a defender and out of bounds. They'll have another chance. Superb block from the Japan defender, and the hosts survive.
Japan back on attack to get the second quarter underway, some sturdy defence from NZ captain Tarrant stemming the tide.
That'll do us for the opening quarter. Japan has certainly had the run of play after their stunner of an early goal, but the Kiwis will be satisfied to have levelled despite their lacklustre start.
12 mins - GOAL NEW ZEALAND
The Kiwis level the scores courtesy of a penalty corner, Nick Wilson on hand to tap in the rebound.

Anthems and obligatory stick touches done and dusted, and we are underway.
We're about eight minutes away from the start of play between the Black Sticks Men and Japan. Overcast and extremely muggy condition in Tokyo, humidity at 86 percent.

They can't though, Australia win the penalty through Lachie Anderson, and that's halftime.
1:36pm: 7 mins - NZ 0 AUS 12
Switching to the rugby sevens, where Australia have taken a 7-0 early lead over the All Blacks sevens.
Make that 12-0, Josh Coward scores a second try for the Aussies!
The conversion's no good though.
