Tommy Morrison (January 2, 1969 – September 1, 2013) was an American professional boxer and mixed martial artist who competed from 1988 to 2009. Best known for his left hook and formidable punching power, Morrison won the World Boxing Organization heavyweight title in 1993 with a unanimous decision victory over George Foreman. He lost the title in his second defense to Michael Bentt that same year. Morrison's other boxing highlights include his fight with Ray Mercer in 1991. In 1995, he won the minor International Boxing Council heavyweight title when he defeated Donovan Ruddock by technical knockout (TKO). He retired from boxing in 1996 after he tested positive for HIV. Morrison is also known for his acting career, having starred alongside Sylvester Stallone in the 1990 film Rocky V as Tommy Gunn.
Morrison made a brief comeback to boxing from 2007 to 2008 when the Nevada commission lifted the indefinite worldwide suspension in July 2006, and briefly dabbled in the world of MMA.
