Morbidelli to the medical centre for checks.
Acosta takes fourth from DiGia at Turn 3.
Bezzecchi's lead is down to 1.3s across the line as Quartararo pushes.
Marquez takes third from DiGia at the last corner.
Huge crash for Morbidelli. His leathers came open as he bounced through the gravel. Rear end went away on the entry to Turn 8.
Bezzecchi's lead is now 1.7s over Quartararo, who is the fastest rider on the track now. DiGia third, Marc Marquez fourth and Acosta fifth.
Morbidelli has crashed out of second place at Turn 8. That looks like a big crash.
Bezzecchi sets the fastest lap and extends his lead to eight tenths.
Zarco has slumped to 10th. That medium rear choice is not working out right now.
Quartararo has made a great start. He's up to third. Bezzecchi's lead is up to 0.7s.
Onto lap two, Bezzecchi leads Morbidelli, Marquez fails to get DiGia at Turns 1 and 2.

Marc Marquez leads into Turn 1 but runs wide! Bezzecchi leads from Morbidelli. Marquez is down to fifth.
We've only had one wet race this year, which was the French Grand Prix - where Johann Zarco won.
He'll be a big threat this afternoon for a first sprint victory.
This is the first wet sprint since the 2023 British Grand Prix, which Alex Marquez won for Gresini Ducati.
The warm-up lap is underway. We are just moments away from racing in Germany!
Michelin has now confirmed that change for Zarco.
Zarco appears to have now switched to the medium soft rear. Marini has too.
Zarco also looks like he's gone back to the medium front. That could be a smart move, as the harder rain tyres work better than the soft when the track starts to dry.
Small delay to the schedule. A 2:10pm start time has been pencilled in following the red flag in Moto3 qualy earlier.
However, the timing screen suggests a late change to the soft front for second-placed Johann Zarco.
Michelin has confirmed everyone is on the soft rear rain tyre, medium front.
Five minutes to go and the rain appears to have eased.
This sprint will be run over 15 laps. Everyone is going to the grid on the soft rain tyre currently.
As pitlane opens for the sighting lap, the rain is falling at the Sachsenring.
