The announcement will come a day after the N.B.A. said the game would be played. General Manager Glen Grunwald of the Knicks and his Nets counterpart, Billy King, confirmed the postponement.

The game was to be the first regular-season contest at the newly opened arena, which was built above a subway and Long Island Rail Road transportation hub. But fans were going to find it nearly impossible to reach the arena because all subway and rail service was knocked out because of flooding. Some of it has since been restored.

NEW YORK -- The highly-anticipated regular-season opener Thursday between the Brooklyn Nets and the New York Knicks, which was to be the first NBA regular-season game at the $1 billion Barclays Center, has been postponed due to the devastation caused by Hurricane Sandy, the Nets confirmed.

At this point, a makeup date has not been announced.

The NBA announced on Tuesday that the game would take place as scheduled. But shutdowns of mass transit due to the hurricane wouldve caused significant problems for fans trying to attend the game.
