Former Heisman Trophy winner and NFL superstar, Herschel Walker, has signed a multi-fight deal with Strikeforce.

The two-time Pro Bowl participant will begin his 12 week training camp with American Kickboxing Academy in California next month. Walker, who will compete at heavyweight, will be sharpening up his mixed martial arts skills with standouts such as Josh Thompson, Jon Fitch, Josh Koscheck, and Mike Swick. He will train under Bob Cook.

The 6 foot 1, 220 pound athlete already has a fifth degree black belt in Tae Kwon Do.

“I’ve been training for several years.  I would play college football games on Saturday and then compete in martial arts tournaments on Sunday after church, I’m now looking forward to opening up another chapter in my life and to competing in MMA,” Walker said.

He played 12 seasons in the NFL, with four different teams. Walker became the only player to gain 4,000 yards in three different ways: rushing, receiving, and kickoff returns. In 1994, Walker became the only player in NFL history to record a 90 plus yard reception, a 90 plus yard run, and a 90 plus yard kickoff return in one season.

At 47 years old, Walker will be looking to triumph in a different sport. He knows what he is getting into, and is confident that his skills will help him be successful in the fight game.

“I will go in there and test myself against any 20 year old. 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.”

There is no word yet, on who Walker’s first opponent will be.
