Hockenheim boss Georg Seiler has confirmed reports that the German Grand Prix will drop off the 2017 calendar.

Reports said that because a race deal could not be struck for 2017, Hockenheim will go and next year's calendar will shrink to 20 grands prix.

Seiler confirmed: "We have noted that a Formula 1 event for Germany is no longer on the 2017 calendar.

"This is regrettable, but not surprising since a date was only reserved and there was no contract for the Hockenheimring."

The circuit chief continued: "There was no offer in which all economic risks were excluded, which was always our condition to be a possible venue for 2017."

Lewis Hamilton won this year's iteration of the race.
