Snowmobile rider Caleb Moore remains in critical condition after a crash at the Winter X Games in Aspen and is being closely monitored.
His family thanked Moore's fans for their support Monday and asked for their prayers.
The 25-year-old was performing a flip Thursday when he clipped the top of a jump and went over the handlebars. The snowmobile rolled over him, but he walked off the course with help and went to a hospital with a concussion.
While there, he developed bleeding around his heart and was flown to Grand Junction for surgery Friday. His family said Sunday that Moore then had a secondary complication involving his brain. They didn't provide details.
"Caleb is not doing good at all," his grandfather Charles Moore told the Denver Post on Monday. "The prognosis is not good at all. It's almost certain he's not going to make it."
Later Monday, Moore's mother, Michele, posted on Facebook: "There may be some misinformation out there right now, from his mom, just let me say that Caleb is still critical but he is definitely fighting, it's time for you prayer warriors to fight too. I appreciate each and every one of you. Tonite at 7:00(mt), 8:00 (ct) I ask you to join us as we lift up our voices to God in one accord. Who will join us?"
Moore's younger brother, Colten, also crashed in the competition and sustained a separated pelvis.
