Organisers of the Brazilian Grand Prix are not confirming reports that the Interlagos race this year might be delayed.
F1 chief executive Bernie Ecclestone on Thursday admitted he had ruled out rescheduling the Bahrain Grand Prix in August.
"It's too hot for the public to sit in the grandstand at 40-odd degrees," he told the BBC.
"We will have a look and see what we can do, how we can swap things around a bit. Maybe we can change it with Brazil, or something like that," added Ecclestone.
The suggestion is that Interlagos' November 27 date could be pushed back to December; a move that could be controversial due to the encroaching Brazilian football season.
A spokesman for the Brazilian Grand Prix told Globo Esporte that the race's organisers have not been consulted or asked about a possible date change.
The spokesman reiterated that November 25-27 is the official date for this year's race; the last on the 2011 calendar.
Ecclestone said on Thursday that a decision about the Bahrain rescheduling is likely next Tuesday, when the World Motor Sport Council sits in Paris.
