Injury has shut down Paralympian Cameron Rahles-Rahbula's fourth and final Games, with the alpine skier ruled out of all of his five events.
The 30-year-old one-legged skier fell while training for the downhill speed event on Wednesday, and had to be carried from the race area in a medi-cab.
MRI and CT scans revealed damage to the Vancouver dual bronze medallist's right knee and ankle, and a small fracture at the top of his tibia near his knee joint.
Rahles-Rahbula had already pulled out of the downhill, Super-G and super-combined, with the hope he would be fit to compete in the technical events starting late in the week.
But further scans have shown his knee and ankle won't be healed in time for him to compete in the giant slalom and slalom, which start later in the week.
"Ski racing has its high risks and this is something that happened," Rahles-Rahbula said.
"It was one of those accidents that freakishly occur. And that's probably the most disappointing part of it - that it wasn't something you expect to happen."
The veteran skier retired five months ago to spend more time with family, before Australian Paralympic Committee cajoled the him into the Sochi team.
He carried the Australian flag in Friday night's opening ceremony, wearing crutches to keep the weight off his injured right leg.
Despite having his wife Emily and two-year-old son Archie in Sochi to watch him race, Rahles-Rahbula will still live in the athletes' village so he could be near his teammates.
"I'm going to encourage the group as they each have a big role to play over this week. Our goals haven't changed so if I can help in any way I'll be there," he said.
Competition continues on Sunday with Australia's Toby Kane and Mitchell Gourley contesting the men's standing Super-G.
