Herschel Walker will be making his mixed martial arts debut at the tender age of 47. Most fans remember the former Georgia Bulldog for winning the Heisman Trophy in 1982 before going on to star on the professional gridiron. What many don’t remember were his accomplishments on the track as a collegian and his Olympic run as a bobsledder.

The eclectic athlete sat down with Sherdog.com at his San Jose training camp to discuss his love for martial arts and his long history of competition. The Pro Bowler talks about how his MMA baptism has gone at the heralded American Kickboxing Academy as well as his reasoning behind deciding to fight.
