I've been hooked on The Extreme Sports Channel recently and can happily spend all day watching the skateboarders, wakeboarders, BMXers and white water rafters.

While watching the other day I started wondering whether there was an extreme sports athlete who might be a suitable candidate for Amputee of the Week. It didn't take me long to find one.

Jon Comer from Dallas, Texas is a professional skateboarder. At the age of four he was struck by a car. His right foot was injured in the smash and was amputated three years later.

But a little detail like that didn't stop Jon from reaching his goal. He's the first professional skateboarder with a prosthetic leg and a film has just been made about his life.

Jon Comer is this week's tailsliding, kick-flipping, ollie grabbing Amputee of the Week.



Another noteworthy extreme sporting amputee is below-knee amp snowboarder Thayne Mahler.
