Team GB cyclist Katie Archibald, who won gold medals at the 2016 and 2020 Olympics, will miss next month's Games in Paris after breaking her leg in a freak accident at home.
Archibald, 30, who was expected to be named in her country's cycling squad on Monday, confirmed the extent of her injury and her subsequent absence from the Olympics in a post on Instagram on Thursday.
"I tripped over a step in the garden and managed to, somehow, dislocate my ankle; break my tibia and fibula; and rip two ligaments off the bone. What the heck," Archibald said.
"That was on Tuesday, and since then I've been in full princess mode.
"Had surgery yesterday to pin the bones back together and reattach the ligaments. Then hopefully this afternoon I'll be going home.
"A hundred thank yous for the fabulous doctors, nurses, radiographers, porters, physios, surgeons and more at the Manchester Royal Infirmary.
"A hundred apologies for what this means for the Olympic team, which I've been told won't involve me."
Archibald won gold in the women's team pursuit at the 2016 Olympics in Rio, a silver in the same event at Tokyo in 2020, and gold in the madison.
