Former Heisman Trophy winner Herschel Walker has signed an agreement with Strikeforce.

The former NFL running back will immediately enter an 8-to-12 week training camp with the American Kickboxing Academy in San Jose, Calif.

Strikeforce director of communications Mike Afromowitz said it’s too early to speculate when the 47-year-old will make his debut with the organization but it will probably be sometime in 2010.

“This isn’t a publicity stunt or a gimmick,” Afromowitz said. “Herschel Walker has tremendous athleticism, and he has always shown that off the gridiron. He’s accomplished a lot in his life and in the world of sports. His accomplishments speak for themselves, and we hope that his athleticism can transition into a successful MMA career.”

Although Walker is known for his football career, he does have a fifth-degree black belt in Tae Kwon Do and competed in the 1992 Winter Olympics in the two-man bobsled, finishing seventh.
