In the constructors' table, Mercedes and Ferrari are separated by four points, while there is a fierce battle between Williams, Haas, Alfa Romeo and AlphaTauri for seventh position, with significant financial rewards on offer for triumphing.
FP1 will get under way at 9:30am GMT with FP2 following at 1pm GMT.
And, with that, it completes the final Friday of the 2023 season. Join us just before 1030 GMT tomorrow for the build-up to the last practice of the year. Bye for now.
Verstappen was not entirely comfortable in his Red Bull but the lack of running after Sainz and Hulkenberg's crashes means we're all a little in the dark.
Perez demotes the Mercedes man a place, though, as the second Red Bull now takes fifth spot, just two tenths down on his team-mate Verstappen in third.
Hairy moment for Verstappen there as he gets caught out by a late call from the team to say Piastri was on a fast lap as the Red Bull driver emerges from the pits on softs.
The Red Bulls now move up to ninth and 12th as they continue on the mediums - but that still leaves them behind Norris, who is the top driver to use the yellow-walled rubber in seventh.
Norris is the first to set a time and jumps to the top of the leaderboard with a 1m25.625s, that is quickly beaten by Piastri and then Bottas while Hulkenberg watches on from the sidelines at Turn 1.
Replays show Verstappen almost colliding with the Mercedes drivers in the tunnel and the Red Bull was nearly in the wall there when trying to pass, you guessed it, Hamilton.
So, when we said earlier about the drivers potentially getting 35 minutes of running in that session, that's instantly gone out of the window. Therefore teams will be going into qualifying very much on the back foot.
"Lost it exit of Turn 1," says Hulkenberg, who just ran ever so slightly wide out of the corner and that sent him spinning hard into the barriers on the inside.
