Snowmobiler in critical condition after Winter X

DENVER (AP) — Snowmobiler Caleb Moore was in critical condition Tuesday in a Colorado hospital after a dramatic crash at the

Winter X Games in Aspen, and a relative said the family wasn't hopeful about the 25-year-old's chances for survival.

Moore was performing a flip Thursday when he clipped the top of a jump and went over the handlebars and landed face first

into the snow. The snowmobile rolled over him, but he walked off with help and went to a hospital with a concussion.

Moore later developed bleeding around his heart and was flown to a hospital in Grand Junction for surgery. The family later

said that Moore, of Krum, Texas, also had a complication involving his brain.

"Caleb is not doing good at all," Caleb's grandfather Charles Moore told The Denver Post. "The prognosis is not good at all.

It's almost certain he's not going to make it."

A family spokeswoman reissued a statement Tuesday thanking fans, friends and family for their support and asked for continued

prayers. The family declined further comment.

A separate accident on Thursday left Moore's younger brother, Colten, with a separated pelvis at Winter X, an increasingly

popular event that showcases the world's best action sports athletes in a festival atmosphere.

The safety of the snowmobile events has

fallen under scrutiny with several recent accidents and mishaps. In

addition to the

crashes by the Moore brothers, there also was a scary scene when a

runaway sled veered into the crowd Sunday night after the

rider fell off during a jump gone wrong.

In that incident, snowmobiling newcomer Jackson Strong tumbled off his machine during the best trick competition. The throttle

stuck on the 450-pound sled and it swerved straight toward the crowd as fans scurried out of the way.

In a statement, X Games officials said their thoughts and prayers were with Caleb and his family. They also said that they've

paid close attention to safety issues during the event's 18-year history.

"Still, when the world's best compete at the highest level in any sport, risks remain. Caleb is a four-time X Games medalist

who fell short on his rotation on a move he has landed several times previously," the statement said.

To help defray the medical costs, a website

has been set up for the family. There's a picture of Moore on the site

and a message

that reads: "Caleb Moore is an inspiration to us all and we want

to support him and his family so they may stay strong during

this difficult time. If you are not familiar with Caleb, he lives

life to the fullest.

"The world knows Caleb as a brilliant freestyle rider, but his family and friends know him as a fun-loving and deeply loyal

person."

In addition, Strong pledged to auction off his outfit from Winter X and donate the proceeds to the Moore family.

Moore grew up racing all-terrain vehicles in

Texas and crossed over into snowmobiling after he got tired of running

around

a track and because it offered better sponsorship opportunities,

his agent, D.C. Vaught, said. Two weeks after Vaught said

he taught the 17-year-old Caleb to do a backflip, he said he was

ready for prime time, and joined Vaught's road show, including

a trip to Europe.

"Whatever he wanted to do, he did it," Vaught said.

He said Moore set up a practice ramp 70-feet long and 10-feet deep in Krum, a town of about 5,000 people 50 miles northwest

of Dallas that rarely sees snow and where snowmobiles are as rare as toboggans.

Caleb began launching his snowmobile into pools of foam a month before the 2010 X Games. After a brief training run on snow

ramps in Michigan, Vaught said he joined the big leagues and never looked back. In the off-months, he still uses the foam

pit in Texas for practice.

Tucker Hibbert, who won his sixth straight SnoCross title at Winter X, hopes all these unfortunate incidents aren't what people

think of when they think about snowmobiling.

"Obviously, at the X Games, you're seeing

the most extreme side of our sport," said Hibbert, who's from Pelican

Rapids, Minn.

"It's definitely dangerous and exciting all at the same time. But

it's also a lot different than what snowmobiling is in general.

"Friends and family riding around, going

down the trails, having fun riding snowmobiles, is quite a bit different

than hitting

a 100-foot ramp and doing double backflips. Naturally, you'll see

some injuries and some pretty big crashes when you're pushing

the limits."

Vaught said Moore's only previous injury was a bruised hip that sent him to the hospital last year, where he was treated and

released.

"In sports, everybody makes mistakes, even if it's rare. Caleb made a mistake. That's it," said Vaught, who witnessed Moore's

crash.

The spills at Winter X weren't just limited

to snowmobiles. Rose Battersby suffered a lumbar spine fracture in a

wipeout on

a practice run before the skiing slopestyle competition. She was

transported to Denver on Sunday and had feeling in all extremities,

according to X Games officials.

Soon after her crash, Ashley Battersby, who's not related to Rose, wiped out on the course and slid into the fencing. Battersby

was down for at least 30 minutes before being carted off on a sled and taken to a local hospital with a knee injury.

There also was a bad wipeout in the snowboard big air competition, when Halldor Helgason of Iceland suffered a concussion

when he over-rotated on a flip. He raised his hand to salute the crowd as he was being taken off the icy course.

Moore's crash came just over a year after one of the most high-profile deaths in the extreme sports community.

Canadian freestyle icon Sarah Burke died Jan. 19, 2012, after sustaining irreversible brain damage in a training accident

in Park City, Utah. The 29-year-old was a pioneer in the sport and a driving force behind the inclusion of slopestyle and

halfpipe skiing at next year's Winter Games in Sochi.
