DENVER (AP) — Caleb Moore, an innovative freestyle snowmobile rider who was hurt in a dramatic crash at the Winter X Games in Colorado, died Thursday morning. He was 25.

Moore had been staying at a hospital in Grand Junction since the crash in Aspen one week before. Family spokeswoman Chelsea Lawson confirmed his death.

A former all-terrain vehicle racer, Moore switched over to snowmobiles as a teenager and didn't take long to rise to the top of his sport. He won four Winter X Games medals, including a bronze last season when his younger brother, Colten, captured gold.
