Mobb Deep rapper Prodigy got a break in Manhattan Supreme Court Tuesday when a judge postponed his sentencing to give doctors time to gather medical records documenting his sickle cell anemia.

Prodigy, whose real name is Albert Johnson, 33, was supposed to begin a 3-1/2-year sentence in state prison for carrying a loaded, unregistered .22-caliber gun in his $150,000 bulletproof SUV in 2006.

But Supreme Court Justice Edward McLaughlin decided the rapper's doctors should get five weeks to produce records documenting his life-long illness.

McLaughlin agreed to talk to state correction officials about assigning the Mobb Deep star to a prison with easy access to medical personnel.

Johnson's lawyer, Irving Cohen, said his client has been in and out of hospitals his entire life with sickle cell disease, a genetic, incurable *lo** disorder that can lead to organ damage, stroke and other problems.

Johnson has claimed cops unsuccessfully tried to get him to implicate superstar rapper 50 Cent in crimes. Johnson said he refused to cooperate.
