Former heavyweight champ is making a comeback

Former World Boxing Organization heavyweight champion Tommy Morrison is staging a comeback and also contesting a positive HIV test that ended his career more than a decade ago. He claimed that the HIV test was inaccurate." I'm negative and I've always been negative and that should be the end of it," Morrison said.

Morrison won the WBO title in 1993 by defeating the formidable George Foreman. He lost it later that year. Morrison, who was featured in the movie "Rocky V," also served a couple of years in an Arkansas prison on drug and weapons charges. He announced he had human immunodeficiency virus in February 1996 and last fought in Japan that November, knocking out Marcus Rhode in the first round.

Steve Allred, athletic commissioner for the state of West Virginia, said on Tuesday he approved Morrison's participation in the bout after reviewing medical records and consulting with the Association of Boxing Commissions' medical review committee. 

The 38-year-old will face John Castle in a four-round bout on Thursday at Mountaineer Racetrack and Gaming Resort. He has signed a contract with Top Rank promoters for at least eight fights this year.
