The NBA will investigate additional allegations by former referee Tim Donaghy that were scheduled for publication in a book that has been canceled by its publisher.

In the book excerpts, which have been published online, Donaghy offered more details of alleged game manipulation by other referees. The NBA and the U.S. Attorney's Office for the Eastern District of New York investigated Donaghy's initial claims and did not find anyone else culpable.

Elizabeth Ventura, the NBA's senior vice president of communications, issued the following statement to CBSSports.com and other news outlets:

"In 2008 Mr. Donaghy's allegations were thoroughly investigated by the FBI and the U.S. Attorney's Office. We are reassured that the U.S. Government completed its investigation finding that the only criminal conduct was that of Mr. Donaghy.

"We take any question regarding the integrity of our game extremely seriously. At the time Mr. Donaghy?s crimes came to light, we appointed Lawrence B. Pedowitz, a former Chief of the Criminal Division in the U.S. Attorney's office of the Southern District of New York, to lead a comprehensive independent review of the NBA's officiating program. Mr. Pedowitz's review revealed that the NBA?s core values of neutrality and accountability were not compromised by anyone other than Mr. Donaghy.

"As with all allegations concerning the integrity of our officiating program, these latest assertions by Mr. Donaghy will be turned over to Mr. Pedowitz for a complete review."
