GRAND JUNCTION, Colo. (AP) — Snowmobiler Caleb Moore remains in critical condition after a dramatic crash at the Winter X Games in Aspen.

Moore's grandfather told The Denver Post the prognosis isn't good and that it's "almost certain" the 25-year-old won't recover. The 25-year-old was performing a flip Thursday when he clipped the top of a jump and went over the handlebars.
