The 25-year-old innovative freestyle snowmobile rider Caleb Moore has died after being injured in a crash last week during the Winter X Games in Colorado.
Family spokeswoman Chelsea Lawson says Moore died Thursday morning.
He had been staying at a hospital in Grand Junction.
Moore was attempting a backflip on Jan. 24 in the freestyle event in Aspen when the skis on his 450-pound snowmobile caught the lip of the landing area, sending him flying over the handlebars.
Moore landed face-first into the snow, and his snowmobile rolled over him.
He was able to walking away with help and went to a hospital for a concussion.
Moore developed bleeding around his heart and was flown to Grand Junction for surgery.
His family later said that Moore, of Krum, Texas, suffered a complication involving his brain.
