Tim Donaghy telephoned a fellow NBA referee 134 times during the period when he was betting on NBA games, according to a report yesterday, a connection that appears to validate concerns that Donaghy might not have been the only referee involved in gambling.

Fox News New York, citing court documents and phone records it obtained, reported that Donaghy made the calls to referee Scott Foster between October 2006 and April 2007.

Donaghy, 41, a Havertown native, has pleaded guilty to providing inside information to bookmakers on games during those seven months. He said he was paid when the teams the bookmakers bet won. He faces 33 months in prison when sentenced on July 29.

The report provided no indication on the nature of the calls between Donaghy and Foster. But it noted that the only person the disgraced referee telephoned more frequently than Foster was Thomas Martino, one of two high school friends who wagered with the information Donaghy provided.

Those calls between Donaghy and Foster, according to the report, occurred before and after 54 of the 57 games Donaghy officiated in that time span.

Foster, 41, a native of Silver Spring, Md., told Fox he was not aware of any investigation focused on him. He would not comment on his ties to Donaghy or on the calls themselves.

Donaghy's attorney, John Lauro, did not immediately return telephone and e-mail messages.

An NBA spokesman said only that the league's probe into the Donaghy case by Lawrence Pedowitz, appointed last year by commissioner David Stern, is continuing and that it did not know of any related investigations.

However, law-enforcement officials in New York told Fox that the FBI was investigating all who turned up on Donaghy's phone records.

Fox's report said most of the calls between the two referees occurred before and after games Donaghy officiated and admitted betting on. It said the most calls Donaghy made to any other NBA referee during that period was 13.

Fox listed, as an example, Donaghy's telephone activity on Dec. 30, 2006.

10:34 a.m. - Donaghy calls Foster.

10:35 a.m. - Donaghy calls another referee.

10:36 a.m. - Donaghy calls Martino.

10:39 a.m. - Donaghy calls Foster.

5:15 p.m. - Donaghy calls Martino.

5:23 p.m. - Donaghy calls Martino.

7 p.m. - Donaghy referees a game in which Orlando beat Miami, 97-68.

8 p.m. - Foster referees a game in which Memphis beat Toronto, 110-104.

11:27 p.m. - Foster and Donaghy speak.

11:38 p.m. - Foster and Donaghy speak.

The NBA has tried to portray Donaghy as what Stern termed a "rogue referee," one who was acting without the assistance or knowledge of any colleagues. The league has dismissed charges he made in court filings, including those that the NBA may have been involved in game-fixing by pressuring referees to go easy on star players.

In a related matter yesterday, the government adjusted its figures on the restitution it claims Donaghy, Martino and the third defendant, James Battista, owe the NBA as a result of their criminal activity.

In a letter to U.S. District Court Judge Carol Amon, assistant U.S. attorney Jeffrey Goldberg lowered the share of the $233,317 owed by Martino and Battista and added it to Donaghy's total.

Martino and Battista have also pleaded guilty and will be sentenced July 24.
