Professional snowmobiler has died from injuries he sustained during a horrific crash during the Aspen X Games last week.
Caleb Moore passed away this morning in Colorado, a family spokesperson said.
Moore's family declined to release further details about the death, but stated on Sunday that he had suffered a "brain complication" stemming from the accident ... on top of a severe concussion and bleeding of the heart.
Moore was competing at the snowmobile freestyle final last Thursday when his 450-pound snowmobile flipped over and landed on top of him.
ESPN released a statement Tuesday, saying, "We've worked closely on safety issues with athletes, course designers and other experts for each of the 18 years of X Games. Still, when the world's best compete at the highest level in any sport, risks remain."
Caleb - once an avid all-terrain vehicle rider -- was a 4-time X Games medalist who first began competing in 2010, after just one month of practicing on snowmobiles.
