No restart time confirmed yet but it will be a 21-lap race with grid positions based on Superpole results.
TV images showing Petrucci being carried away from the turn 13 gravel trap on a stretcher. He's been taken to the medical centre.
Red flag as the riders get to turn one on lap two. No perimeter road here, which is maybe the cause for the stoppage after Petrucci's crash.
Petrucci has crashed at turn 13, looks like he high-sided on entry.
It's lights out in Most for Race 1 and it's a holeshot for Bulega, then Montella and Lecuona second and third. Surra fourth, then Sam Lowes.
Riders are off on their warm-up lap ahead of Race 1.
Van der Mark, of course, is riding in place of Miguel Oliveira this weekend, the Portuguese missing out after his injury in Hungary two weeks ago.
Shaun Muir spoke to WorldSBK.com on Friday and explained that there is "no fixed timeline" for Oliveira's return.

Pit lane has opened in Most and the riders have headed to the grid ahead of this 22-lap Race 1.
Still dry ahead of Race 1 but the clouds are looking increasingly dark overhead.
Slightly warmer than this morning at 16C air temperature and 34C track temperature.
In case you missed it earlier, Alvaro Bautista will not be taking part in the remainder of this weekend in Czechia after he crashed in FP3 this morning and broke his right ankle.
Full story here.

Welcome back to live coverage of today’s WorldSBK action from Most, where Race 1 is due to start in around 40 minutes at 14:00 local time.
Chequered flag is out in Czechia and it's Bulega on pole for the sixth round in succession.
Montella and Lecuona make it five from five Ducati front row lockouts in 2026.
Sam Lowes fourth, then Surra and Gerloff complete the second row.
Bassani, Baldassarri, and Petrucci on row three. Manzi completes the top-10 ahead of Vierge and van der Mark on row four.
Bulega's smashed them all, 1m29.635s, he's 0.4s clear of the field, which now has Lecuona in P2.
Montella now to pole, 1m30.051s is a new lap record, beating Razgatlioglu's from 2024.
Everyone back in the pits now ahead of the second run. Top 10 is:
- Lecuona
- Bulega
- Montella
- Gerloff
- Baldassarri
- Petrucci
- Bassani
- Vierge
- A. Lowes
- S. Lowes
6 minutes to go.
Lecuona now to provisional pole by 0.038s over Bulega.
Shortly before Bulega set his lap, Alex Lowes crashed at turn one, his third of the weekend and second of the day. He's sat in eighth at the moment.
Gerloff with an early benchmark at 1m30.637s, but he's quickly beaten by Bulega and Montella, the former down to a 30.203s.
Pit lane is open in Most and we are underway for 15 minutes of Superpole.
If you're like us and have only just heard the term 'medial malleolus' for the first time this morning, the two-time champion has effectively fractured the inner bump of his ankle.
Alvaro Bautista has been declared unfit after his FP3 crash having suffered a right medial malleolus fracture.
Fairly chilly this morning in Most, 13C air temperature, but 27C track temperature should be fairly workable for the riders in this Superpole session, which is now just over five minutes away.
Bulega's win streak is well-documented in WorldSBK by now so it almost goes under the radar that he's taken every pole position this season as well. Of course, he took pole in Jerez last year as well, so a pole today would be his sixth in succession and fifth from five in 2026.
In terms of where that kind of run would put him compared to the best ever, Jonathan Rea opened the 2021 season with a run of eight consecutive poles.
