But Ecclestone, 83, has now told the Wall Street Journal that the New Jersey street race is off again.
He said the postponement, likely to be confirmed with the FIA's publication of the official 2014 calendar on Wednesday, is "for lots and lots and lots of reasons".
"We are not satisfied it's going to happen in time," said Ecclestone. "What we're aiming for is 2015."
The newspaper said race promoter Leo Hindery did not return a call seeking comment.
And the Bloomberg news agency quoted a spokesman as saying the organisers will comment after the publication of the calendar.
