Walker was eventually drafted in 1985 by The Dallas Cowboys and established himself as a premiere running back in the league. In 1986, he was the driving force behind a historic trade that sent in to The Minnesota Vikings in exchange for five players and six draft picks.

In 12 NFL seasons with four different teams, he became the only player to gain 4,000 yards three different ways - rushing, receiving, and kickoff returns. He is one of six players to exceed 60 touchdowns rushing and 20 touchdowns receiving and is the only player in NFL history to register a 90 plus yard reception, a 90 plus yard run, and a 90 plus yard kickoff return, all in one season (1994).

Off the gridiron, Walker has achieved a handful of feats, including a seventh place finish in the 1992 Winter Olympics two-man bobsled competition. He also nearly made the Olympic sprint relay team.

Now 47 years of age, Walker, a native of Wrightsville, Georgia, will look to conquer a whole new world. It is a challenge he is extremely optimistic about.

"I will go in there and test myself against any 20 year old," said Walker. "I know there will be naysayers and I'm fine with that. I want to prove to people who sit on a couch and don't do anything but criticize other people that, if you're a true athlete or martial artist, you're not old until you can't get up and walk around anymore. MMA fighters are said to be some of the best athletes in the world, my plan at the age of 47 is to show the world I am still one of the best athletes as well"
