Here's some tragic news in the aftermath of the 2013 Winter X Games. Snowmobiler Caleb Moore, who was injured last week after he failed to complete a back flip during the freestyle final in Aspen, Colo., died earlier today. Although doctors initially believed that Moore suffered a concussion during the accident, it was later discovered that he had actually sustained a heart contusion.

"This morning Caleb Moore passed away," his family said in a statement. "He will be truly missed and never forgotten. The family wishes to express their deep gratitude for all the prayers and support they have received from all the fans, friends, and family around the world that Caleb has inspired. They would also like to thank the physicians and medical staff at both Aspen Valley Hospital and St. Mary's Hospital, Grand Junction for their care and dedication. At this time, the family will not be making any other public statements. They continue to decline interviews. Thank you for continuing to respect the family's privacy during this difficult time. Arrangements for a celebration of life are being made and an announcement will be made in the coming days."

Very sad.
