Donnie Walsh has revealed to the New York Post that guard Cuttino Mobley, who recently retired for medical reasons, is still occupying a roster spot with the team.

It was believed that New York had a spot open to sign a player such as Patrick Ewing Jr. to a 10 day contract, or to make a 2-for-1 trade, but this is not yet the case.

According to the piece, the Knicks won't waive Mobley until the league decides how to classify his retirement. They are on the verge of filing a $4.5 million disabled player exception application. An NBA official said the Knicks have not yet filed the application. The Knicks have to wait until the ruling is in.

Walsh is hoping the league rules Mobley's career-ending heart condition - hypertrophic cardiomyopathy - occurred after his Nov. 21 trade to the Knicks.
