Racing in the giant slalom started at an altitude of 10,340 feet (3,152 meters) and the 26-year-old German won by retaining his first-run lead. The victory ended runner-up Marcel Hirscher's five-race winning streak in the event.
Hirscher, the Olympic champion in giant slalom, could yet be awarded his 60th World Cup race win. FIS anti-doping rules state oxygen tanks cannot be brought to race venues, and "competition results achieved after the use of the equipment shall be automatically disqualified."
The World Anti-Doping Agency allows "supplemental oxygen administered by inhalation, but not intravenously," though notes that sports bodies could choose to prohibit it. "Athletes must check the rules that apply to supplemental oxygen use with the sporting authorities governing the events they compete in," WADA guidelines state.
Germany team director Wolfgang Maier acknowledged to the DPA agency that the team made a mistake but had not cheated. Luitz will be eligible to race in Saturday's giant slalom in Val d'Isere, France, pending the investigation, FIS said.
The incident could potentially add to Luitz's reputation as an unlucky skier. At the 2014 Sochi Olympics, he was poised for the second-fastest time in the first run of the giant slalom. He then hooked a ski around the simple final gate and fell over the finish line as the ski flew away from his boot. He was disqualified for straddling the gate.
