US group asks Mexico officials not to allow Morrison to fight.
The Association of Boxing Commissions has no oversight of the sport in Mexico, but the organization is imploring officials there to bar heavyweight Tommy Morrison from fighting Saturday night.
Morrison, a one-time top contender who first tested positive in 1996 for HIV, the virus that causes AIDS, is scheduled to face Matt Weishaar (3-0-2, 1 KO) in Leon, Mexico, in a four-round bout to be televised as part of Top Rank's "Latin Fury" pay-per-view card headlined by Julio Cesar Chavez Jr. against Jose Celaya. Morrison has said repeatedly in the past year that numerous subsequent blood tests have shown he is not infected with HIV.
