From Champ to actor. Former World Champion boxer Mike Tyson is expanding his acting career. He will guest star on an episode of “Law & Order: SVU” scheduled to air Feb. 6, 2013. Tyson plays a character who is a victim of a crime and….. oops, we can’t tell you the story line!! You have to watch and see it yourself. After being drug free for the past five years, Tyson says I’m “happy with myself”. He and his wife Kiki are busy doing big things.
