The Nets, Knicks and Miami Heat will battle over the next two-plus weeks to avoid the Play-In Tournament.
The race tightened up a bit on Thursday when Brooklyn and New York both lost winnable games.
The Nets were outscored 12-2 in the final two minutes of their 116-114 loss to Cleveland.
The Knicks lost, 111-106, in Orlando -- their third straight defeat.
It sets up an intriguing five day-stretch in the battle for the fifth seed.
Brooklyn plays at Miami on Saturday and the Knicks host the Heat on Wednesday.
New York (42-33) is a game up in the loss column on both Brooklyn (39-34) and Miami (40-34).
