Herschel Walker's MMA career

From a dominant college football player, to author of a book and his mental health problems to now approaching a new challenge, Mixed Martial Arts. At the age of 47 Herschel is starting a new career in the cage, but he's not the first former NFL player to try this new career. He has signed a multi-fight contract with promoter Strikeforce. Walker will begin a 12-week training camp next month in San Jose, Calif., with the American Kickboxing Academy.
