Lillehammer (RWH) The International Luge Federation’s Technical Director, Christian Eigentler of Austria, will be unable to attend the Viessmann World Cup in the Norwegian town of Lillehammer because of a pinched nerve in his back. Bjørn Dyrdahl of Norway, who was the FIL’s Technical Delegate for many years, only retiring during the last Olympic winter, will stand in for him. So the predecessor is following on from his successor. 32-year-old Eigentler left Winterberg on Sunday for his Austrian home, where he is to rest and recuperate. The doctors expect the Tyrolean to be back in office by the 45th FIL World Championships being held in the Latvian town of Sigulda on February 14-15, 2015. Eigentler hurt his back at the Viessmann World Cup in Winterberg (GER) while helping an athlete from Latvia leave the track after a crash. He was taken to the hospital and diagnosed with a pinched nerve.
