Oh no! This is seriously awful.
We previously mentioned that Caleb Moore was competing in the Winter X Games when a mistimed flip landed his snowmobile on top of him.
He went to the hospital for a concussion, then it was discovered there was bleeding around his heart.
Another complication with his brain left him in critical condition.
Sadly, he's passed away.
Caleb Moore is the snowmobile star who was just seriously injured at this year's Winter X Games.
We previously mentioned that he mistimed a big air backflip and brought his 450-pound snowmobile down on top of himself!
Originally, it was only thought he had a concussion until he had to be rushed to a nearby hospital for bleeding around his heart.
Sadly, things are even more serious. He is currently in critical condition after a secondary complication involving his brain.
Caleb's grandfather said that the prognosis isn't good. He said it's "almost certain" that Caleb won't recover.
That's so awful! He's only 25.
We hope he makes a miraculous recovery!
Check out the video (above) to see his violent crash at this year's Winter X Games.

This is a big deal, you guys, because nobody has nabbed two national figure skating titles in a row… since Michelle Kwan in 2005!!
Ashley Wagner has just matched that!! She clinched the win in Omaha, and she's so good that she won it in spite of two falls! Daaaamn, girl!
There are a few questions lingering, though:

Caleb Moore is a snowmobile star and was competing at this year's Winter X Games.
He is a big name in the pro snowmobile game so it was a big deal when he spectacularly mistimed a big air backflip and landed his 450-pound snowmobile on top of himself!

Alessandra Ambrosio not only looks wonderful on the runway, but she also kills the scene on powdery slopes!!
The HAWT supermodel hit up the Oakley Learn To Ride in collaboration with New Era event on Saturday in Park City, Utah, and we must say, homegirl had it going on.
When we first saw this video, we had no idea about the injuries and death that resulted from it. While the video isn't graphic in any way, it is very unsettling to know that one of the men in the Zorb — an inflatable sphere — was killed due to injuries sustained in their descent.
We are shocked by how irresponsible this is, and apparently this is an attraction at a resort.
Obviously there weren't enough safety measures in place.
Watch above, even just to seen an example of how not to spend a holiday.

Vicki Gunvalson, star of Real Housewives of Orange County, is lucky to be alive after she fell off a mountain!!
Well, more like down a mountain, but still, scary stuff!
Vicki was skiing down a slope in Park City, Utah just before the New Year.
While flying down the mountain, a snowboarder apparently cut her off and she ended up falling face first down the mountain!
