Snowmobiler Caleb Moore died Thursday morning from injuries sustained in a crash at the Winter X Games one week ago. He was 25 years old. The Moore family has declined to release any details about Caleb’s death, but it was reported that he’d suffered a “brain complication” in addition to his other injuries.

The family spokeswoman, Chelsea Lawson, released a statement on behalf of the Moores this morning:

This morning Caleb Moore passed away. 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.

ESPN, which hosts the X Games, also released a statement:

We are deeply saddened by Caleb Moore's passing and our thoughts and prayers go out to his parents, Wade and Michelle, his brother, Colten, and the entire Moore family. He will be remembered for his natural passion for life and his deep love for his family and friends, and he will always be an inspiration to everyone he touched in the action sports community.

As a result of this accident we will conduct a thorough review of this discipline and adopt any appropriate changes to future X Games.

For 18 years we have worked closely on safety issues with athletes, course designers, and other experts. Still, 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.

Moore’s death is the first in the 17-year history of the Winter X Games.
