The plan is still for Kimi Antonelli to drive today for Mercedes, reports Lewis Larkam in Abu Dhabi.
Antonelli is due to arrive at the circuit is one hour.
He was ill over the weekend, and pulled out of the F2 race.
Yuki Tsunoda and Isack Hadjar will drive for Red Bull today.
Both are hoping for promotions for the F1 2025 season.
A decision on Sergio Perez has yet to be confirmed, amid doubt he will return next season.
If Red Bull opt to replace Max Verstappen's teammate, RB's Tsunoda or Liam Lawson would get the nod.
Hadjar, the Red Bull junior, would then step into the RB.
Yuki Tsunoda is finally getting the chance to drive a Red Bull F1 car in Abu Dhabi.
And just like that, the first hour of running has flown by!
Sainz has set the pace for Williams with a 1m24.620s ahead of former Ferrari teammate Charles Leclerc.
The top 10 order is as follows:
- Sainz (Williams)
- C. Leclerc (Ferrari)
- Doohan (Alpine)
- O'Ward (McLaren)
- Hadjar (Red Bull)
- Browning (Williams)
- Norris (McLaren)
- Crawford (Aston Martin)
- Aron (Alpine)
- Tsunoda (Red Bull)
One driver who was scheduled to take part but is yet to make an appearance is Andrea Kimi Antonelli.
Lewis Hamilton's replacement at Mercedes for 2025 was due to drive this year's W15 today but so far he has not been in action, with Frederik Vesti driving for Mercedes alongside George Russell so far.
It remains to be seen whether Antonelli - who pulled out of last weekend's F2 finale with illness - will run at some point later today.
Carlos Sainz is currently fastest, for what it's worth, having posted a 1m25.258s in his Williams.
Everyone has been out getting some early laps in during the first half an hour or so of running this monring.
Green light at the end of the pitlane and testing is underway at the Yas Marina Circuit.
One notable absentee today is Lewis Hamilton.
While several drivers will get the chance to make an early start on preparations for their new teams, Hamilton will not be among them. Instead, his first Ferrari run will have to wait until early next year.
This is due to his contractual commitments with Mercedes. You can find out full details here.
The test is split into two sessions - one in the morning and one in the afternoon.
All 10 teams are in action and will be fielding two cars each - one for Pirelli tyre testing (which takes place this morning) and one for a rookie who will take part in the young driver part of the test this afternoon.
Here is the full information on the driver line-up for today.
