Three-time Olympic ski jump champion Thomas Morgenstern has been hospitalised after suffering a huge crash in training in Austria.
The 27-year-old was preparing for this weekend's ski flying World Cup in Bad Mitterndorff when he had the accident.
Video footage shows Morgenstern losing his balance when airborne before turning over and landing on his back and head. According to reports, he lost consciousness for a while but was able to speak shortly afterward.
The Austrian was given first aid on the hill before being flown to hospital in Salzburg. The extent of his injuries are not yet known.
"Fortunately he was responsive, Thomas can move arms and legs. That's very important," team physician Herbert Leitner said. "He asked me what happened."
"We can only hope for the best," he added. "This really hurts because we are all very close. Thomas is the heart of this team."
The accident comes less than a month after Morgenstern was hospitalised after suffering facial injuries when he crashed during a World Cup event in Titisee-Neustadt, Germany.
