Morrison tested positive for HIV in 1996 before a fight with Arthur Weathers, effectively ending his boxing career. In the years that followed, he denied having HIV and also challenged the existence of the virus. Trisha Morrison, who married Morrison in 2011, picked up that fight, and in a recent interview with ESPN.com insisted that Morrison had Guillain-Barre Syndrome, not HIV. He had already run afoul of the law in 1993, when he pleaded guilty to assaulting a college student. He also dealt with weapons charges and multiple DUI incidents over the years. He was sentenced to two years in prison in 2000, and another year was added to his sentence in 2002 for violating parole.
