Career
Morrison's professional boxing career effectively ended when he tested positive for HIV in 1996. Beginning in 2006, Morrison attempted a comeback, stating that he did not have HIV and, later, that HIV is a "myth." His claims are refuted by boxing and medical authorities.
After his enforced retirement in 1996, Morrison has been charged with multiple assault, weapon, intoxication, and drug offenses. He was sentenced to jail on several occasions, and served part of one sentence in 2000–2001.
