SWISS skier Urs Kryenbuehl was airlifted to hospital following a horror 87mph crash at the men's downhill World Cup in Kitzbuehel.
The 26-year-old was racing in Austria when he lost control on the final jump.
He lay motionless after hitting the snow with incredible force and slid down around 50 metres to the finish line.
Reports from Swiss Ski suggest he was conscious and recognised one of his trainers by the time he was flown away by helicopter for emergency medical treatment.
But others report he has severe head injuries with medical information about his exact condition yet to be released.
The legendary Streif track is widely regarded as the most dangerous to ski in the World Cup series.
And Kryenbuehl's horrific smash was not the first serious incident of the day.
Just 30 minutes earlier, American Ryan Cochran-Siegle crashed into a safety net and suffered a shoulder injury.
