In addition to the announcement of the 2009-10 salary cap, NBA teams received tentative projections from the league office warning that the cap is estimated to drop to somewhere between $50.4 million and $53.6 million for the 2010-11 season.

The official league memorandum, obtained by ESPN.com, forecasts a dip in basketball-related income in the 2009-10 season of 2.5 percent to 5 percent, which threatens to take the 2010-11 cap down some $5 million to $8 million from last season's $58.7 million salary cap.
