The giant slalom competitor underwent surgery last month to reconstruct his right anterior cruciate ligament, after he ruptured it during training in New Zealand.
That's ruled out any last hope of him qualifying for February's Winter Games in Pyeongchang.
"It wasn't just my ACL that I did in the end: it was I did my ACL rupture completely, I tore my medial ligaments as well and my meniscus and I had a little fracture in there too for good measure," he said.
