Mixed martials arts newcomer Herschel Walker told a website that the sport should be part of the Olympics and also needs a union for competitors.
Walker, a Heisman Trophy winner who went on to a successful NFL career, told MMAjunkie.com that his current sport should be part of the Olympics program.
"I don't know why they don't make it an Olympic sport," he said. "It's like five sports rolled up into one. You've got karate, judo, jiu-jitsu, boxing and wrestling all rolled up into one. There are more countries that have MMA fighters than countries that have basketball teams or baseball teams."
Walker has Olympic experience as a bobsledder. He also had the security of a union while playing in the NFL and wants fans to understand the benefits for the competitors.
"I think the fighters in the sport are just now starting to make good money," Walker told the website. "The promoters are making good money, and sooner or later the fighters should start making good money. Some of them make OK money but not great money. But the way the contracts are written for the UFC, sooner or later there needs to be a union. I think a union should come in."
Walker won his MMA debut and donated his prize money to charity.
