The NBA approved a trade yesterday that sends F-C Eddy Curry and veteran C Antonio Davis from Chicago to the Knicks for Fs Tim Thomas, Michael Sweetney and Jermaine Jackson. The Bulls also get a conditional first-round draft pick in 2006, two second-round selections in the future and the option of exchanging picks with New York at a later draft.

The 22-year-old Curry, drafted out of Thornwood High School in South Holland, Ill., missed the last 13 games of his fourth NBA season and the playoffs after he had an irregular heartbeat diagnosed. The Bulls had insisted that Curry take a DNA test to determine whether he's susceptible to a potentially fatal heart problem, a request Curry balked at, saying it violated his privacy.

Several prominent cardiologists cleared Curry to play, but Barry Maron, a renowned specialist in hypertrophic cardiomyopathy, suggested the DNA test to see if Curry was susceptible to the same ailment that killed former Celtics G Reggie Lewis and Loyola Marymount star Hank Gathers.

After three sluggish years, Curry had broken through to lead the Bulls last season with 16.1 points per game.
