Disgraced NBA referee Tim Donaghy is expected to turn over the names of former colleagues who bet at golf courses, racetracks and casinos during the season, and are involved in football pools, sources told the

.

While the activities are not illegal, they would violate the referees' contracts that prohibit all gambling except at horse tracks in the offseason.

Donaghy, 40, pleaded guilty last Wednesday in federal court in Brooklyn, N.Y., to conspiring to commit wire fraud and conspiring to transmit wagering information across state lines. He reportedly gave federal prosecutors information that will implicate about 20 other referees - about a third of the officiating staff - as part of his cooperation with government officials.

"I don't know if there are 20 NBA refs even that close to Tim Donaghy," a source close to one referee said. "Donaghy was pretty much an outcast by a number of referees, especially the local guys. They threw their arms up a while ago with him. They didn't want anything to do with him, so I don't where this comes from."

The referees are under a league-imposed gag order.

A local law-enforcement source said this seems to be a case of Donaghy trying to turn over anything he can to potentially lighten his sentence. Donaghy is facing a maximum of 25 years in prison, fines up to $500,000 and at least $30,000 in restitution. "When the FBI went into this area to ask questions, they didn't ask about any other NBA refs, they asked about what Donaghy was doing," the source said.

The league has said it has received no evidence that anyone other than Donaghy is involved in betting on games. *
