Caleb Moore died today of injuries suffered during last week's horrific snowmobile crash at the Winter X Games in Aspen, Colo., his family revealed today in a statement. Moore, 25, hurt himself when he botched the landing on a backflip, bringing his entire 450-pound snowmobile crashing down on his head and chest, CNN explains. "He will be truly missed and never forgotten," his family said in a statement, thanking "fans, friends, and family around the world" for their "prayers and support."
ESPN released a statement saying it was "deeply saddened by Caleb Moore's passing," and promising that the incident would prompt a "thorough review of this discipline." While it promised to change the event if necessary in future X-Games, it added that "when the world's best compete at the highest level in any sport, risks remain. Caleb was a four-time X Games medalist attempting a move he has landed several times previously." (Read more Caleb Moore stories.)
