The 30-year-old Gisin lost control before a jump midway down Saturday, flew into the air and landed awkwardly on his side and back, right in the middle of the Saslong course's famous camel bumps. He was then bumped into the air again and the back of his head hit the snow in a second impact.
He was lying motionless on the course before doctors and trainers arrived for assistance. A rescue helicopter landed on the snow and took off for the hospital in nearby Bolzano with Gisin onboard after he had received treatment for almost a half-hour.
"His condition is stable enough that he can be flown back to Switzerland tonight for further diagnoses," a statement from the Swiss ski team said. "The exact diagnoses of his injuries we expect Sunday afternoon."
Gisin already had a concussion following a crash in Kitzbuehel, Austria, in 2015. His best career results are two fifth-place finishes in the Kitzbuehel downhill last season and in 2016. Gisin's sisters are both highly successful skiers.
Dominique Gisin won gold in downhill at the 2014 Sochi Olympics, and Michelle Gisin won combined at the Pyeongchang Games in February. Aleksander Aamodt Kilde of Norway won Saturday's race.
