ATLANTIC CITY, N.J., JAN. 19 -- Along with the weather, talk of a possible June meeting between the premier heavyweights, Mike Tyson and Michael Spinks, heated up today, causing more of a stir on the Boardwalk than Friday night's Tyson-Larry Holmes world championship fight.

In the first thaw in the frosty relations between the Tyson and Spinks camps, Tyson comanager Bill Cayton has invited Spinks' manager, Butch Lewis, to meet the Tyson brain trust sometime this week to begin negotiations on Tyson-Spinks to take place here June 24.

Cayton called a June meeting "still viable," but said it depended on whether the two camps could sit down to begin talks this week. Otherwise, Cayton said, he and his partner, Jim Jacobs, would proceed with arrangements for another opponent for Tyson, probably Frank Bruno June 17 in London.

"This could be a breaking of the ice," said Lewis, from his home in Delaware. He is due here Thursday. "I'm willing to go into a room with them. I want to try to make a fight."

But Lewis said he would not meet with Tyson's managers if any "preconditions" exist -- which appears to be the case. Sticking to his earlier word, Cayton said Lewis could not be part of the promotion, which would be the biggest boxing attraction since Leonard-Hagler last April. "I'm not going to be dictated to," said Lewis.

Spinks, who defeated Holmes twice and in his last fight demolished Gerry Cooney, continues to work out -- "nothing serious, just keeping in shape," said Lewis. He added that he is working on another possible fight for Spinks in the event he can't quickly come to terms with Tyson's people, but declined to say with whom.

Spinks would have met Tyson earlier had he not dropped out of the Home Box Office heavyweight elimination series to fight Cooney. Now, said Cayton, the next move is Lewis'.

Meanwhile, Holmes continued to maintain the lowest profile anyone could remember for a participant in a heavyweight title fight.

The 38-year-old who was heavyweight champion for 7 1/2 years but has not fought since April 1986, is not expected here from his home in Easton, Pa., until Thursday, the eve of the fight.

This means he will be absent for the traditional prefight news conference Wednesday. In one of his last pronouncements before going into seclusion, Holmes (48-2) said, "I'm going to knock him out. To beat Tyson {21 years old, 31-0, 28 knockouts}, it would take a good left with lateral movement -- two of the things I do best."
