Two years later, while attending Kilgore College on a full scholarship for football, Lewis violated his probation and was sentenced to five years in prison, but ended up serving three and a half. A week after being released, Lewis was introduced to mixed martial arts by a friend and, while working as a tow-truck driver, continued with boxing under the tutelage of George Foreman. After dominating in his first professional mixed martial arts fight, Lewis decided to focus on mixed martial arts.
