Albrecht, 29, lost control and fell into the safety nets as he prepared for this weekend’s World Cup race at the Rocky Mountain ski resort.
He was taken to a hospital in Calgary by helicopter for treatment of what the Swiss Ski Federation called a “complex injury”.
National team trainer Osi Inglin told Swiss media that Albrecht’s head was not injured.
A native of Valais who has won four World Cup victories since debuting on the slopes at the age of 19, Albrecht has suffered a number of spectacular falls in his career.
In January 2009, he crashed on the final jump at Kitzbühel, Austria while travelling at 140 kilometres an hour in a training run.
Suffering from brain and lung trauma, he was put in an induced coma for 16 days.
Albrecht was bidding to return to downhill form this season after struggling over the past few seasons.
His latest accident comes days after the Swiss Ski Federation announced that another one of Switzerland’s top skiers, Beat Feuz, will miss the rest of 2012-2013 season as he has not fully recovered from a knee operation last spring.
Feuz, 25, runner-up to Austria’s Marcel Hirscher in the overall World Cup standings last year, did not take part in the season opener at Sölden in Austria.
Among other Swiss hopefuls in Lake Louise, Didier Défago put in the best performance in Thursday’s training run with a fifth-place finish.
