TEAM GB medal hopeful Jake Wightman has been forced to withdraw from the Olympics.
The 800m runner has picked up a hamstring injury which means he will not be on the start line next week.
Team GB have called up Elliot Giles in his place, with the 30-year-old set to participate in his third Olympics.
Giles failed to reach the final in his previous two appearances at Rio and Tokyo, and his personal best is almost a second slower than Wightman.
Wightman has been plagued by injuries over the last few years and missed the British Championships earlier this year due to a calf problem.
He won 1500m gold at the 2022 World Championships, becoming the first Brit to win that title since Steve Cram in 1983.

The 30-year-old then decided to focus on 800m and is a two-time British champion in the event, while also being the Scottish record holder.
He finished 10th in the 1500m at his Olympics debut in Tokyo, but was tipped to challenge for a podium place in Paris.
Wightman also missed out on the opportunity to defend his 1500m world title in 2023 as he sustained a freak foot injury during a gym session.
That forced him to spend five weeks in a protective boot as he recovered, with his compatriot and childhood friend Josh Kerr winning gold in his place.

Wightman is not the only Team GB medal hopeful to be struck down by injury, as skateboarding sensation Sky Brown dislocated her shoulder just days before she was set to compete for gold.
Brown, 16, is now being looked after by Team GB's medical team.
It is still hoped that she will be able to compete in the women's Park skateboarding on August 6 and go for gold.
