Australia’s Olympic hockey player Tom Craig has been released from police custody and apologised to his family and teammates after being arrested in Paris for buying cocaine.

“I’d firstly like to apologise for what has occurred in the last 24 hours. I made a terrible mistake. I take full responsibility for my actions,” Craig said as he left police offices.

“My actions are my own and in no way, reflect the values of my family, my teammates, my friends, my sport, and the Australian Olympic team. I’ve embarrassed you all. I’m truly sorry,” he added.

So encouraging stuff for Great Britain’s men’s four, who were stripped of their silver medal from Tokyo after CJ Ujah’s doping violation. Richard Kilty and Nethaneel Mitchell-Blake were part of that quartet alongside Zharnel Hughes – will Hughes be fit enough for the final? Regardless, you’d back Team GB to be in the medal mix if they fire.

“Me and Nethaneel do this like clockwork,” veteran Kilty tells the BBC. “We’ve been here a million times. It’s amazing to get out here with these young flying machines. It’s amazing to get out there with our fastest time of the year, and we’ll definitely push on for the final. We’ve got much more in us.”

So the qualifiers for the final are…

The Americans should take it at a canter if fully-loaded and functioning, but it’ll be anyone’s game, really, for the other medals.

A nightmare for Jamaica and only fourth for the sprinting powerhouse! Kishane Thompson took the baton with 100m to go and had it all to do after two dreadful changeovers, and though he surges from sixth, it is not enough! Jamaica miss the 4x100m final – Japan and Italy take the two spots available to fastest losers.

China, France and Canada snatch the three automatic qualifying spots, though seven of the quartets in the first heat were quicker. Thompson and his teammates look up the big screen, perplexed, perturbed and bidding adieu to Paris 2024.

Grace Reid is through in seventh, with a score of 290.05.

There is also joy for Yasmin Harper, who sneaks through into the final in 12th.

The final will take place at 2pm tomorrow.

A show of force from the United States, 37.47secs and clear air to the rest of the field. South Africa wisely utilise Akani Simbine (fourth again in the individual 100m) to anchor, and he brings them home impressively, taking them from out of contention to second.

Great Britain are third and into the final, with Louie Hinchcliffe going very well on relay debut. An anxious wait for defending champions Italy – having taken that stunning gold in Tokyo, they finish fifth in the heat and will be reliant on slow times in the second of them.

Over to the men, then, with Great Britain and the USA in heat one of two. Zharnel Hughes is still nursing the hamstring issue that forced his withdrawal from the 200 metres, which means a first run for Louie Hinchcliffe in the British quartet. We know the NCAA Champion is rapid, but how will he gel with Jeremiah Azu, Richard Kilty and Nethaneel Mitchell-Blake?

The United States have rested Noah Lyles and Kenny Bednarek, though can still rely on 60m world champion Christian Coleman to provide an explosive start and Fred Kerley to keep things moving smoothly the second leg. You’d imagine Bednarek will take the bend tomorrow night with Lyles to bring it home – that looks a fearsome foursome, assuming they get to the final…

Ahead of the final round, there is still a bit of work to do from Grace Reid, who was ninth after four dives.

Yasmin Harper sits in sixth.

It’s worth remembering that only the top 12 make the final.

A national record for Canada in fourth in that second heat, and they’ll be into the final. The Netherlands, who pipped Nigeria for fifth, also take a fastest losers’ spot.

Here’s your line-up for tomorrow night in order of qualification time:

Storming stuff from the British quartet, clean and quick – 42.03secs, with their two fastest sprinters still to come in. That will please them mightily. Great Britain take heat two from France, with Jamaica a relatively distant third.
