NBA to review new claims by shamed official

The NBA says it will review accusations by former referee Tim Donaghy that were posted online.

The league also says Thursday it has been reassured that an investigation found Donaghy to be the only official involved in criminal conduct. The referees say they are disappointed but not surprised by their former colleague's actions.

Donaghy admitted taking cash payoffs from gamblers for picks on games, including ones he officiated. He was sentenced to 15 months for conspiracy to engage in wire fraud and transmitting betting information through interstate commerce.

Donaghy accuses fellow referees of misconduct in excerpts that appeared on the Web site deadspin.com. The publisher says it won't go forward with the book.

NETS EXERCISE OPTIONS ON 3: The New Jersey Nets have exercised contract options on starters Courtney Lee, Brook Lopez and Yi Jianlian for the 2010-11 seasons.

The Nets on Thursday also declined to exercise the fourth-year contract option on forward Sean Williams, the team's first-round draft pick in 2007 and the 17th pick overall.

The options that the Nets picked up on Lopez and Lee were for their third seasons. Lopez will earn $2.41 million, while Lee will get $1.34 million. The option on Yi is for his fourth season and it will earn him just over $4 million.

Williams would have earned $2.5 million had the team pick up his fourth-year option
