[UPDATE: Less than 24 hours after this post, Caleb Moore died.]

Caleb Moore remains in serious condition at a Colorado hospital. Moore crashed his snowmobile at the Winter X Games Friday night. He walked away from the crash, but later had emergency heart surgery when doctors found internal bleeding. Now, they are fearing for his life. From the Denver Post:

“Caleb is not doing good at all,” Caleb’s grandfather Charles Moore told The Denver Post Monday afternoon. “The prognosis is not good at all. It’s almost certain he’s not going to make it.”

“Caleb is in critical condition and is being closely monitored,” family spokeswoman Chelsea Lawson said Monday evening. “The Moores want to express their gratitude to all of Caleb’s fans, friends and family for their strong support and ask for continued prayers in the coming days. The family will not be making any other public statements for the time being. Thank you for respecting the family’s privacy during this difficult time.”

There are also complications with Moore’s brain. This weekend Moore’s mother said that he suffered his 11th concussion in the accident.
