A 25-year-old 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.
