American skier TJ Lanning has been flown back to the United States after he fractured a vertebra in his neck and dislocated a knee in a high-speed crash during a World Cup downhill at Lake Louise in Canada.

Lanning was transported from a Calgary hospital in a medically equipped Lear jet to Vail, Colorado, where he will undergo further tests at a local hospital.

American TJ Lanning will miss the rest of the season after suffering a broken vertebrae in his neck along with a dislocated left knee in a crash.

The 25-year-old has been transferred to a hospital in Vail, Colorado after the crash in Saturday’s downhill at Lake Louise.

“These are serious injuries but the vertebrae fracture is not displaced and does not appear to require surgery at this time,” said US team doctor Richard Quincy

Lanning had to be airlifted off the downhill course on Whitehorn Mountain after losing control on the steep Fallaway section.

Lanning had two top-10 places in World Cup downhills last season finished in the top 25 overall in downhill and super G despite missing the final three months of the season with a torn anterior cruciate ligament.
