Scottish distance runner Andrew Butchart will miss the Commonwealth Games in April after suffering a broken bone in his foot.
Butchart, from Dunblane, said he "felt a sharp pain in my right foot" in a 3,000m race in New York last weekend.
"I knew what it was straightaway," Butchart said in an Instagram post. "After an MRI in Boston it was confirmed - a fractured navicular."
Butchart added he was "heartbroken" and "won't be racing for a while."
He will not recover in time for the Commonwealth Games on Australia's Gold Coast, which begin in less than eight weeks, on 4 April.
Butchart, 26, finished sixth in the 5,000m at the Rio 2016 Olympic Games.
Two other Scottish athletes - pole vaulter Jax Thoirs and high jumper Emma Nuttall - have also been forced to withdraw from the team.
Thoirs, 24, had started the indoor season promisingly and was considered a possible medal hope on the Gold Coast. But a blood clot issue affected his health, and he is now to have surgery on a rib problem which will keep him out of the Games.
Nuttall, 25, was nursing a knee injury early in the New Year but further diagnosis confirmed tendinopathy in her left knee.
She has had to put training and competition on hold until early in the summer season - with the Games coming too soon.
