Hockenheim boss Georg Seiler says the circuit cannot host this year's German Grand Prix due to the short turnaround to sell tickets.
In January F1 boss Bernie Ecclestone said Hockenheim would host the Germany race on July 19 when the Nurburgring failed to reached a deal admid financial problems. Hockenheim and Nurburgring had previously alternated the grand prix every year.
But circuit boss Georg Seiler says it is impossible for Hockenheim to host this year's race due to the limited turnaround.
"We do not have hope the race can be here in Hockenheim," Seiler told Bild. "The moment to organise a race here has passed, otherwise the quality of the event would have suffered."
Seiler added there was not enough time to sell tickets and that the circuit would have been unlikely to reach last year's total of 54,000 race day fans even with the normal period of time to sell.
It means Formula One faces the prospect of no grand prix in a country home to Mercedes and responsible for nine drivers' championships since 2000. Four-time world champion Sebastian Vettel, Nico Rosberg and Nico Hulkenberg are the German drivers on the 2014 grid.
If the German Grand Prix does not go ahead this season's calendar will shrink back to 19 races.
