Caleb Moore had a violent crash Thursday at the Winter X Games Aspen. He wasn’t able to fully rotate on a backflip and his sled tumbled onto him upon impact. It was nasty and not for the faint of heart.

"While Caleb was being evaluated late last night, he developed bleeding around the heart and was urgently flighted to Grand Junction [Colo.]," according to an X Games Medical report issued Friday morning. "He underwent surgery this morning. The procedure went well, and Caleb is currently in ICU with a heart contusion."

Moore’s brother, Colton, was also involved in a crash Thursday night, but his injuries are less severe.

Here’s hoping that both of them are able to get back on their feet as quickly as possible.
