LENNOX LEWIS' promoter has advised the former WBC world heavyweight champion to take an AIDS test amid fears that his former rival Tommy Morrison has tested HIV positive.

Former WBO champion Morrison was "medically suspended" just hours before he was due to fight in Las Vegas on Saturday.

The bout would have been his first since October, when he was stopped in the sixth round of a bloody encounter with Lewis.

British promoter Panos Eliades, who handles Lewis' affairs, said the London born fighter was in Jamaica and had not heard about Morrison's suspension.

"We'd better get our man in there (for testing)," Eliades told the New York Daily News. "There was a lot of blood in that fight."

There was silence from Nevada officials and the Morrison camp, but a source told the Associated Press that Morrison had tested positive for HIV.

Marc Ratner, executive director of the Nevada Athletic Commission, said he could provide no specifics on the suspension because of legal constraints.

"I have been instructed very carefully by the attorney general's office not to say anything more," he said. "That is all I can say at this time."

Meanwhile, Lewis' fight against former WBO heavyweight champion Ray Mercer has been confirmed for Madison Square Garden on May 10th.

It will be the ex WBC champion's fourth outing since losing his title and unbeaten record to Oliver McCall in September, 1994.
