The family of injured freestyle snowmobiler, Caleb Moore, has set up a website to help defray medical costs.

Caleb is in critical condition after performing a flip on January 24 at Winter X-Games. He went over the handlebars and the snowmobile rolled over him.

He went to the hospital to be treated for a concussion and developed bleeding around his heart and was flown to Grand Junction for surgery. His family released a statement Sunday that Caleb  had secondary complications involving his brain.

In a statement released Tuesday to the Denver Post, ESPN X Games officials stated: "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 is a four-time X Games medalist who fell short on his rotation on a move he has landed several times previously."
