LONDON -- The promoter of the Mike Tyson-Lou Savarese fight says he doesn't believe Tyson's use of antidepressants will cause the postponement of the heavyweight bout.

"The only way this fight will not take place is if Mike Tyson is injured," promoter Frank Warren said Thursday.

Warren predicted Tyson would easily pass his medical tests in Britain for the June 24 fight in Glasgow, Scotland, but was evasive when it came to the boxer's use of antidepressants.

"The British Board of Boxing Control, as far as I am aware now, is asking Mike Tyson's doctor whether there is any substance to what is being said," Warren said. "That is between him and his doctor to deal with that with the board.

"From what I'm told, from what I've read, people say he's been taking things to tranquilize him, so that cannot be performance-enhancing."

Tyson is in top physical condition for the fight, but Warren added there may be questions about his mental state following the murder of a close friend in New York. Tyson missed two days of training following the death of Darryl Baum, 34.

Tyson delayed his arrival in Britain until Sunday so he could attend the funeral.

"His state of mind up until his friend died was very good, very positive," Warren said.

The fight has been surrounded by controversy.

Women's groups unsuccessfully sought to have Tyson, who served a three-year sentence for a rape conviction, banned from entering the country.

Simon Block, the general secretary of the British Board of Boxing Control, has asked for details on Tyson's medication before deciding whether to authorize the fight.

"Everybody who applies for a license has to provide certain documentation," Block said Wednesday. "He has yet to produce a number of administrative and medical documents in order to be licensed to box in this country ... like he did the last time he was here."

Tyson's use of antidepressants became known following his fight with Evander Holyfield in 1997, in which Tyson bit Holyfield's ear.

In a report released the following year, a team of doctors who examined Tyson portrayed him as turning to antidepressants because of his gloom and lack of self-esteem after the Holyfield fight.

The report, prepared for the Nevada State Boxing Commission, said Tyson had a "constellation of neurobehavioral deficits" that include problems with attention span, memory, reading, spelling and impulse control.

The doctors said Tyson reported having feelings of sadness, hopelessness and helplessness "all my life."
