Australian Olympic snowboarder airlifted to hospital with broken neck
The 35-year-old suffered the injury on Monday but complained of "worsening neck pain" the following day, the Australian Olympic Committee said.
A CT scan identified that his neck was broken in two places and he was put on a helicopter to Milan.
It is one of several injury blows to hit Australia at the Olympics in Italy.
Another snowboarder, Misaki Vaughan, is also out after failing a head injury assessment following a fall on Monday.
"My heart breaks on their behalf," Australia's chef de mission Alisa Camplin-Warner said.
