MUTTENZ, Switzerland -- World Cup leader Pirmin Zurbriggen, who injured his left knee Saturday while winning a downhill event at Kitzbuehel, underwent knee surgery Sunday night.
Following arthroscopic surgery, part of his inner meniscus was removed.
A statement released by the Swiss Ski Federation said arthroscopic inspection of the joint revealed that the cartilage ligaments were unaffected.
Zurbriggen was to start rehabilitating gymnastics Monday and his condition gave reason to hope he would be able to participate at the World Ski Championships in Bormio.
However, the statement said that both the federation and Zurbriggen himself would put his health above any other considerationand not risk it by premature competition.
'I was told that in the best circumstances, I would be out of action for one week. I will not resume racing before I feel fit, and I'll be happy if I'm ready for the world championships,' Zurbriggen said.
Zurbriggen suffered the injury after crossing the finish line of Saturday's downhill when he slammed into the ground at 80 miles per hour.
