Ecclestone had confirmed in January he made a bid for the financially-troubled track.
"We want to make sure there is a formula one race in Germany every year in the future," he said.
But last week, it emerged that Ecclestone was not among the latest candidates - entities from Dusseldorf and the US, and a private equity firm - in the running to buy the Nurburgring.
Germany's Sport Bild now reports that German driver and reigning world champion Vettel could be involved in a Nurburgring buyout bid.
But the Austrian news agency APA quoted his spokesman Britta Roeske as saying: "There's nothing to it (the report)."
The current bidding process will reportedly conclude at the end of March.
