The New York Post (Marc Berman) reports: Cuttino Mobley is strongly mulling a medical retirement because of an enlarged heart condition and could make the announcement tomorrow, according to a person familiar with the situation. Mobley, 33, still has one more heart test left today in Minnesota. It had been reported that Mobley had signed a waiver with the Clippers to release them of liability if he had heart problems. If Mobley, obtained in the Zach Randolph trade from the Clippers, retires, it would free open a roster spot and save the Knicks about 75 percent of the $18. 9 million left on his pact because of insurance.
