Arnold (Red) Auerbach, 61, architect of 13 National Basketball Association titles with the Boston Celtics, signed a "multiyear" contract yesterday with the team's new owner, John Y. Brown.

Turning down an offer from the New York Knicks he called "one of the most flattering moments in my career," Auerbach, who has been with the Celtics 28 years, the players started talking to me and it all built up. I was stopped on the streets and people told me to stay in Boston.

"It was primarily an emotional thing," said the man whose teams won eight consecutive NBA championships between 1958 and 1966. "Nobody lies to leave a loser."

Adrian Paulen, president of the International Amateur Athletic Federation, said in Paris that Dwight Stones will be banned "for life" for "professionalism."

Along with Stones, a bronze medal winner at Munich and former world record high jumper (7 feet 1-inches), runner Francie Larrieu, javelin thrower Kate Schmid and Pentathlete Jane Frederick have been banished for competiting in television's "Superstars" competition.

Amateur athletes are allowed to participate in so-called professional events as long as they turn over money won to their national federations, in this case the AAU.

"We are not unaware that Stones give the money to his club (the Dessert Oasis Track Club), but Stones is the only memberr of te club," said Paulen.

"Anyway, most of the money paid to the "Superstars" must be reverted to the national federation and this has not been done."

The Detroit Tigers have confirmed that 23-year-old right-hander Mark Fidrych will start pitching again, this time for the organization's farm club in Lakeland, Fla.

Fidrych has been unable to pitch since April because of pain in his throwing arm. First team doctors, then other medical specialists have tried to find the cause of the pain.

After watching "The Bird" pitch a "painless" batting practise in Seattle Thursday night, Tiger executives decided another couple of weeks in the minors might be just the cure.
