EAST RUTHERFORD, N.J., DEC. 3 -- The New Jersey Nets today signed former San Antonio Spurs point guard Johnny Moore to a contract for the rest of the season and reportedly will drop their former No. 1 draft choice, Dwayne (Pearl) Washington.

Moore, waived by the Spurs last month, has a year left on a guaranteed contract that reportedly pays him about $400,000 this season. He will get $75,000 from the Nets, the rest from the Spurs, published reports said. The Nets wouldn't disclose terms of the contract.

Moore has spent his seven-year career with the Spurs, averaging 10.8 points. He led the NBA in 1981-82 with 9.6 assists per game and is the Spurs all-time leader with 3,783.

He has had problems with desert fever, a rare form of meningitis. He became ill Dec. 21, 1985, before a Denver game and was diagnosed the following month. He missed the rest of the 1985-86 season and played in 55 games last year. The Nets probably will waive rookie guard Jamie Waller to make room for him.

Washington lost his starting job to John Bagley last week and is averaging eight points and five assists per game.
