Diogo Moreira has had a crash, but LCR says he is ok.
Spanish Grand Prix winner Alex Marquez has now taken over top spot with a 1m36.394s, with Johann Zarco now second on the LCR Honda.
Just over halfway through hour two in session one at the Jerez test, and everyone but Augusto Fernandez has been on track.
The Yamaha test rider looks like he'll have more time on the M1 later this week in some private running.
Aprilia has provided a brief of what its test plan is today.
• Marco Bezzecchi: the work will continue with the testing of several components, including a new front fairing with some aerodynamic innovations.
• Jorge Martin: the programme will mainly focus on evaluating components he has not yet had the opportunity to use, due to missing the winter tests and the tight race weekend schedule. Some aerodynamic tests are also planned.
• Lorenzo Savadori: usual development work, focusing on data collection and the validation of new components.
• There will also be electronic tests, and the factory riders will have the opportunity to test certain components that have already been brought to the track by the Trackhouse MotoGP Team. Thanks to the strong collaboration between the two teams, some of these solutions could also prove of interest to the factory team as well.
Pedro Acosta is now fastest early into hour two of session one with a 1m36.734s.

Ducati gets to work.
Hour one is in the books and Fabio Di Giannantonio leads the way for VR46 Ducati on a 1m36.769s.
Yamaha brought some new parts for the Spanish Grand Prix, but, crucially, it doesn't have a new engine to test. Quartararo wasn't very happy about this at the weekend.
Di Giannantonio improves to second, 0.66s behind Bezzecchi.
For those unaware how a test day in MotoGP works:
The day is split into two sessions, with the chequered flag flown after each. This is followed by a brief practice start session.
The practice start session after session one rolls straight into session two, so there's no official break.
Bezzecchi has found a small lap time gain with a 1m36.769s. He leads Fabio Quartararo and Alex Marquez with 2hrs20mins to go in this session.
LCR will be hoping to build on the strong weekend it enjoyed at the Spanish Grand Prix today in the test.
Toprak Razgatlioglu said he had fun in the last laps of the Spanish Grand Prix, even if the race was generally unenjoyable

Track is getting busier. We've had laps from reigning champion Marc Marquez now, who has instantly gone up to second.
Championship leader Bezzecchi takes over top spot with a 1m36.970s.
Rain on Saturday will have washed away a lot of rubber, so the track today should offer slightly more representative grip conditions to better evaluate new items.
Luca Marini now fastest with a 1m37.539s.
Di Giannantonio has now improved to a 1m37.721s.
Marini heads out on track for Honda.
Di Giannantonio improves to a 1m38.310s.
The best dry lap of the weekend was a 1m35.7s from Friday Practice.
Brad Binder and Luca Marini are now out there.
Intriguingly, Bezzecchi is shadowing Di Giannantonio on track right now. Perhaps he's keen to get a better look at where the Ducati was better than the Aprilia over the weekend?
Di Giannantonio has gone top with a 1m39.036s.
He didn't run any of the new aero parts and other Ducati updates during the Jerez weekend, as he wanted to focus on the good feeling he already had with his GP26.
So, today is his chance to do some development work.
