Sentencing for former NBA referee Tim Donaghy, who pleaded guilty last August to two felony charges - conspiracy to commit wire fraud and transmitting betting information - has been moved back from Friday to April 18 at 9 a.m. in New York.

Donaghy, 41, who grew up in Havertown, admitted Aug. 15 to U.S. District Judge Carol Bagley Amon that he had bet on NBA games, including games he officiated, over four years beginning in 2003. He also admitted that he had provided information to gamblers beginning in December 2006 about which officials would work which games on a particular night - information previously kept secret by the league but now available to the public - along with picking a team on which the gamblers should bet. Donaghy was paid if the team won the game.

Donaghy paid $30,000 to the court in August and faces additional penalties of a $500,000 fine and 25 years in prison. Two men who prosecutors say were part of the gambling ring have been arraigned on wire-fraud charges.

Donaghy, a Cardinal O'Hara and Villanova graduate, originally had been scheduled for sentencing Nov. 9.

The NBA has maintained that information from the FBI as part of the investigation indicates that Donaghy was, in the words of commissioner David Stern, a "rogue, isolated criminal" who was not part of a bigger pattern involving other officials.

The league, however, determined that about half its 58 officials had committed minor violations of the league's policy barring them from being in casinos or engaging in other betting activities. Officials can, in the off-season, bet on horse races at tracks. But the league opted not to punish any of the other officials who committed the infractions.

In addition, the league named former official Bernie Fryer to the new position of assistant director of officials and chief crew coordinator. His job includes assessing crew chief performances and serving as a mentor for younger officials.

Ronnie Nunn, the league's director of officials, was moved from his oversight position in New York to provide roving instruction to referees in the field.

Donaghy, who had officiated in the NBA for 13 years, resigned July 9, just as the case against him was coming to light.
