The Australian Institute of Sport athlete was competing in her second World Cup event of the year in Silvaplana, Switzerland, when she damaged her knee during the competition.
Despite feeling immediate pain, she competed well in the final, finishing third.
Segal will fly home to Melbourne on Thursday and is likely to have minor arthroscopic surgery next week before embarking on an eight week recovery program.
“There was one feature at the very end (of the Silvaplana course), which was not a very difficult feature but it had a flat landing,” Segal said.
“I avoided it in training but I hit it after my first qualification run.
“Because it was such a hard flat landing my knee felt like crunch, instant pain.
”It hasn’t been the best year for me. I was hoping for more. I was looking forward to upping my game in competition. I have been skiing pretty well in training but I have not put together that win-a-competition run that I know I can do.”
Segal is hoping to return to on snow training before the end of the northern hemisphere winter.
