Motorcycle daredevil Clint Ewing is being treated for third-degree burns sustained during a stunt for CMT's [series id="42058"]Tunnel of Fire[/series], one of several shows centering around the network's Bike Week programming.

The accident occurred Wednesday (Aug. 7) in Sturgis, S.D., at the Sturgis Buffalo Chip, one of the biggest motorcycle rallies in the world. According to a CMT press release issued July 22 announcing the Tunnel of Fire special, Ewing intended to break a Guinness world record by "traveling through a towering inferno longer than a football field."

According to Motorcycle USA news website, Ewing was riding a Yamaha sportbike while attempting to ride through a tunnel of fire more than 360 feet long. He made some practice runs through the tunnel before it was ignited for the stunt. He emerged from the flaming tunnel following a crash, but his bike is a total loss. Details about his condition had not been announced Friday (Aug. 9) although plans were underway to transport him to a burn clinic in Los Angeles.

Ewing, a 32-year-old California native, began riding off-road motorcycles when he was in the third grade. As a professional freestyle sportbike rider, he has completed more than 110 events throughout the nation.
