Caleb Moore underwent surgery for a heart contusion Friday morning after he suffered serious injuries in the Snowmobile Freestyle finals Thursday night at X Games Aspen.
Moore came up short on an indy air backflip attempt, augering into the snow as his 450-pound sled tumbled over him. Moore was knocked unconscious in the crash, and he was evaluated for a concussion and other injuries Thursday night.
"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."
As of Saturday evening, Moore was stable and continues to be monitored in the intensive care unit, according to X Games Medical.
The family released a statement through ESPN Sunday afternoon, saying, "Caleb continues to be monitored in ICU. His cardiac injury has led to a secondary complication involving his brain. The Moore family thanks all of Caleb's fans and friends for their support and for respecting their privacy."
His brother Colten Moore, also injured during the Snowmobile Freestyle final, was treated Thursday night at Aspen Valley Hospital for a separation of the pelvis (pubic diastasis) and will not require surgery, according to X Games Medical. Colten Moore was released from the hospital Saturday.
Colten Moore, 23, won gold in the event in 2012, sharing the podium with Caleb, 25, who won bronze. The brothers from Krum, Texas, just north of Dallas, are also known for their showmanship on the Feld Motorsports Nuclear Cowboyz tour.
Daniel Bodin, 28, a third rider who crashed during Thursday's event, was treated for a left wrist injury at Aspen Valley Hospital; X-rays revealed no break.
"I feel terrible about the accidents that happened," said Levi LaVallee, who emerged from Thursday's final to claim his second gold medal in the event (LaVallee previously won in 2008). "But I'm happy I put down a solid run and came out on top to win gold again. It's like, 'Pinch me! Is this for real?' "
