The Sacramento Kings, facing a $10 million lawsuit from the former agent of Corliss Williamson, will not be re-investigated by the NBA amid claims by the agent that the Kings withdrew a "secret" contract promised to Williamson in 1998.

The league conducted an inquiry into the alleged under-the-table deal, in which Williamson's former agent, Elbert Crawford, claims the team promised a seven-year deal worth at least $50 million after Williamson played for $500,000 in the lockout-shortened 1999 season.

The Kings instead bestowed a big-money deal on Vlade Divac in the summer of '99, and Williamson, after firing Crawford, returned to Sacramento for $3.5 million.

"After looking into it, there was not enough to demonstrate a violation," said NBA senior vice president Brian McIntyre.

McIntyre said the investigation in Sacramento began before Minnesota received its hefty punishments for an illegal deal with Joe Smith and continued after the Timberwolves' sentence was announced on Oct. 25, 2000. Smith's contract for the 2000-01 season was voided, and the Timberwolves were fined $3.5 million and docked five first-round draft picks.

NBA commissioner David Stern, who also suspended T-Wolves owner Glen Taylor and general manager Kevin McHale for a year, called the Smith case "a fraud of major proportions."

The league, which had previously investigated reported cases of handshake deals, punished the first violation it could prove, Minnesota's Smith incident, in the harshest terms.

Crawford filed his $10 million suit in California Superior Court in Los Angeles against Kings co-owners Joe and Gavin Maloof, former Kings owner Jim Thomas and Geoff Petrie, team president of basketball operations. According to the suit, which was filed on Wednesday, Sacramento withdrew the $50 million offer after the '99 season.
