(CNN) Olympic skier Lindsey Vonn has broken her arm in training, just weeks into the current ski season.

She sustained the injury in a crash Thursday on Copper Mountain, in Colorado.

"I had successful surgery (Thursday) night in Vail and everyone took great care of me," Vonn said in a Facebook post Friday.

"While I am beyond frustrated by this latest setback, at least my knees are OK and I will return to the slopes as soon as possible, as I always do! Thank you for the continued love and support, it means so much to me."
