The 34-year-old has just returned from an extended injury lay-off and was treated on the slopes for 20 minutes before being taken to hospital in an ambulance helicopter.
He was able to stand on his feet before being hoisted into the helicopter.
- It was incomprehensible that the coach let him start given the medical problems he had in the past.
He had a very severe concussion in training in Garmisch-Partenkirchen in January 2021 and has had huge problems and then he stands up and crashes.
Let's hope it doesn't get any worse now, says SVT Sports expert Pernilla Wiberg.
Up at the starting line, brother Gino Caviezel was waiting to start.
He finished 31st after deciding to run the race after all.
Mauro Caviezel won the Super G Cup in the 2019-20 season.
Race winner Marco Odermatt, started number six, Caviezel was number eight, and was unaffected by the crash.
Aleksander Aamodt Kilde started eleventh and had his charge disrupted before finishing second.
- I felt that the wait had an effect.
It wasn't the same feeling as yesterday, says Kilde to NRK.
