Mike Tyson is searching for a ranked opponent and a doctor. The doctor comes first.

Nevada boxing authorities have given the former heavyweight champion a list of three facilities where he must undergo a psychiatric examination. They also have set a deadline of Monday for the doctors to submit reports on Tyson's mental state.If Tyson is cleared by the doctors, the Nevada Athletic Commission is expected to give the former heavyweight champion a new boxing license on Oct. 3.

"No one wants to go see doctors, but he's eager to get his license back," Shelly Finkel, Tyson's adviser, said Tuesday.

Tyson gets his choice of being examined at the Mayo Clinic in Rochester, Minn.; Massachusetts General Hospital in Boston; or C.F. Menninger Memorial Hospital in Topeka, Kan.

The examination was ordered by the commission following Saturday's six-hour hearing on Tyson's request for reinstatement. He has been banned since the commission revoked his license July 9, 1997, for biting Evander Holyfield's ears.

A letter sent to Tyson and his advisers Monday from the commission said the team of doctors evaluating him must include a psychologist, a psychiatrist and a neuropsychologist. The boxer must be given comprehensive neuropsychological testing as well as an MRI of the brain and a complete drug screen.

In addition, the commission wants the doctors who evaluate Tyson to look at videotape of his fight against Holyfield as well as from post-fight interviews and license reinstatement hearings in New Jersey and Nevada.

Finkel said he was trying to find out which of the three facilities do all the testing required by the commission and whether he could get three doctors to come to Las Vegas on Oct. 3 to be questioned by the commission.

The Mayo Clinic, he said, apparently doesn't do all the testing requested by the commission.

If he regains his license, Tyson's first foe will be a fighter who is ranked. In his first comeback fight after being released from prison in 1995, Tyson knocked out Peter McNeeley in the first round. Both Tyson and Finkel are looking for a stronger opponent this time.

"You want credibility in the person he fights," Finkel said. "We're looking for a rated opponent."

If Tyson is allowed to return to the ring, he is expected to fight in late November or early December, most likely at the MGM Grand hotel-casino in Las Vegas.

Finkel predicted the fight will be bigger than Tyson's comeback against McNeeley, in which he got a $25 million purse. However, the money was split in half by payments he had to make to promoter Don King and his co-managers.
