Sachsenring's MotoGP round is under threat of cancellation as German authorities have banned all mass gatherings until at least the end of August.

The German GP, which registered more than 200,000 visitors over the 2019 race weekend, is due to go ahead on June 21 but with the extended quarantine measures, that is now impossible.

Even a race with no spectators is against the rules as the paddock would still be 1000 strong with just the core technical staff from all three classes.

There are a couple of weekends free in September for races to be run but Dorna still has to find room for Mugello and Jerez which have yet to be given new dates after their postponement.
