Former college football great Herschel Walker will make his mixed martial arts debut Jan. 30 at the age of 47. Yes, 47. After a success college career at Georgia and a somewhat success career in the NFL, Walker has been branching out to other sports. Remember when he was an Olympic bobsledder? Now, it's MMA.
Walker, a fifth degree black belt in Tae Kwon Do, sat down with Sherdog.com in San Jose, Calif., to talk about his reasons for fighting.
