Vienna - Austrian skier Matthias Lanzinger will sue the ruling body FIS for compensation over a crash at a World Cup race in Norway in which he lost his lower leg.

The Austrian Press Agency APA reported on Monday that Lanzinger's lawyer, Manfred Ainedter, has sent an according letter to FIS president Gian-Franco Kasper.

The compensation claim comes in the wake of a report from a Munich doctor who said that Lanzinger's left leg had to be amputated below the knee due to a delay in medical treatment.

Lanzinger, 27, crashed during a super-G in Lillehammer in March. He was first taken to hospital in nearby Lillehammer and then on to a special clinic in Oslo.

Citing the report by the Munich vascular surgeon Bernd Steckmaier, Ainedter said that no appropriate treatment was available in Lillehammer. He also spoke of incorrect treatment in Oslo.

"The report proves that treatment of my client was botch up," Ainedter told APA.

It remains unclear whether the FIS or local organizers are to blame. The FIS denied any negligence in the Lanzinger case. (dpa)
