Jakob Ingebrigtsen failed to qualify for the 1500m semi-final at the World Athletics Championships in Tokyo. He finished eighth in his heat.

Why it matters for Jakob Ingebrigtsen
Ingebrigtsen's failure to qualify is a significant upset, given his status as a top athlete in the sport.
He had not competed outdoors all season due to an injury.
What comes next?
Ingebrigtsen will now focus on the 5,000m event, which he says he is closer to being ready for.

Kerr was the second-fastest from both the first heat and overall.
Ingebrigtsen's heat was won by Jake Wightman, who pipped him to world gold in 2022.
Wightman was full of respect for Ingebrigtsen's effort, saying he couldn't have stepped on the start line at a world champs without racing at all.
Ingebrigtsen's next event will be the 5,000m, where he will look to regain his form.
He will have a couple of days to recover before competing again.
The World Athletics Championships continue in Tokyo, with the 5,000m event upcoming.
Ingebrigtsen's fans will be hoping he can bounce back from this disappointment.
The 5,000m event will be a key test for Ingebrigtsen, who is the reigning champion.
He will face tough competition, but will be looking to regain his title.
The event is scheduled to take place soon, and Ingebrigtsen will be looking to make a strong comeback.
