British six-time Olympic cycling champion Chris Hoy said he recently suffered the "worst" crash of his life as he receives treatment for cancer.
The former track star revealed last year that his cancer was terminal but the 49-year-old has continued to ride his mountain bike.
Hoy said earlier this year that he had entered "a bit of a stability stage" in his treatment.
In an interview with Sky Sports published on Thursday, the Scotsman said he had "smashed his leg up" while riding.
"That's the worst thing that's happened recently," he said. "You just don't bounce like you do when you're younger.
"It was a big one. I'm doing better now, I'm still on crutches, hobbling about."
He added: "Worse things happen. I've been riding bikes for 43 years and it's the worst crash I've ever had."
Only fellow track cyclist Jason Kenny, with seven Olympic golds, is above Hoy in the all-time list of British Olympians.
Hoy also claimed 11 world championship golds during his glittering career.
He announced in February 2024 that he was undergoing treatment for prostate cancer and later that year said the diagnosis was terminal after the cancer spread.
He said he had been told by doctors that he had between two and four years to live.
Hoy said he was "not a massive risk-taker" but wanted to make the most of his life.
"None of us is here forever so you want to make the most of the time you have and do the things you enjoy," he added.
"I've just had an unfortunate spill and it's the way the cookie crumbles. I'm doing all right now. I wasn't doing so well in the immediate aftermath of it, but looking forward to Christmas."
