[Walker] has long been involved in mixed martial arts and is looking at possibly forming a stable of pro athletes who could challenge competitors in the UFC.

"I was in Las Vegas one time and was watching some of the UFC guys train and they were saying they're the best athletes in the world," Walker said. "I said that was a bold statement to make so I challenged it.

"I said, 'Guys, I can put together a couple of athletes who could train in mixed martial arts and I could guarantee we'd give you a run for your money. So now we're looking for different TV stations that want to carry a reality show like that."
