The Edinburgh-born runner won silver after being pipped by USA's Cole Hocker in a new Olympic record.

The much-hyped showdown was billed as a two-horse race with Ingebrigtsen, but Hocker's sprint in the final straight gave him a shock gold and a time of 3:27.65.

Norwegian Ingebrigtsen finished out of the medals in fourth after setting a blistering pace and leading for most of the race.

American Yared Nuguse took bronze but was only a hundredth of a second behind Kerr.

There had been much talk beforehand about Kerr and Ingebrigtsen's apparent dislike for each other after trading barbs over the past year or so.

Kerr's time of 3:27.79 is a British record and the 26-year-old appeared happy with his silver, grabbing a union flag and hugging supporters on a lap of honour.

Speaking trackside, he admitted he'd been focused on gold but said he was "really proud" and that it was a "heck of a step in the right direction".

Kerr, who beat Ingebrigtsen to gold in the World Championships last year, won a bronze at the Tokyo Olympics in 2021.

Other medals for Team GB on Tuesday were a silver for the men's team sprint in the velodrome and a bronze for 16-year-old Sky Brown in the skateboarding.

Boxer Lewis Richardson, from Colchester, also had to settle for a bronze after narrowly losing by split decision in the 71kg semi-final.

He comes away with Britain's only boxing medal of the games - with Team GB staying fifth in the table with 12 golds and 46 medals overall.

Meanwhile, Dina Asher-Smith and Daryll Neita missed out in the 200m final in the last event on track on Tuesday.

Asher-Smith - who was distraught after not making the 100m final - put in a strong performance but finished fourth in 22.22, with Neita in fifth.

America's Gabby Thomas took gold, with 100m champion Julien Alfred in silver and Brittany Brown third.

Asher-Smith was far more upbeat after the race, telling reporters she was "really proud to have held my own" in such a strong field.

Elsewhere, there was heartbreak for Andrea Spendolini-Sirieix earlier in the day, with the British diver in tears after only managing sixth in the 10m platform final despite a strong showing in the semis.

The 19-year-old won a bronze in the synchronised event earlier in the games.
