It's a Ferrari one-two at the top of the timesheets. Carlos Sainz was quickest but here comes his Ferrari pal Charles Leclerc. The Monegasque driver is also on the softs and clocks a 1:38.917 to jump the Spaniard. Fernando Alonso in his Aston Martin is third.

Mechanics running back to the garage to make sure they can get to work on [Lando's] car and know what went wrong with it.
Well done to those Ferrari mechanics.
Sergio Perez needs the escape road at Turn 12 to do a fancy turn in his Red Bull to get himself out of trouble. Meanwhile, Carlos Sainz goes quickest in his patched-up Ferrari with a 1:39.891 on the soft tyre.
We have a Ferrari on track! Carlos Sainz is back up and running after his misfortune in first practice.
Lando Norris cuts the kerb in the final sector but it doesn't matter, as no fans are in the grandstands to see it. The McLaren driver is told to box and is now being given a load of instructions by his engineer.

Nathan: Cancel FP2, get the drivers to bed, give them 90-120 minutes for FP3 tomorrow, then onto quali. Let repair teams work through the night and make sure it’s safe for tomorrow

Looks like Carlos Sainz’s Ferrari could be ready in time for second practice - he's running across the paddock to the garage.

As soon as Rosanna Tennant, Jolyon Palmer, Alice Powell and Andrew Benson pop up on Sports Extra, I'll let you know.
Put the kettle on.
Image source, Getty ImagesThere has been a mixed reaction to holding a race in Sin City. We already know it was high on Daniel Ricciardo's wish list but Max Verstappen thinks this weekend's race may be more style over substance.
The triple world champion thinks the Las Vegas Grand Prix will be "99% show and 1% sporting event", and the spectacle around the race is something he is "not looking forward".
Verstappen added: "They are still going to make money whether I like it or not. But I am also not going to fake it. I voice my opinion in positive and negative things. That's just how I am.
"Some people like show a bit more, I don't like it at all. I just grew up looking at the performance side of things. I like to be in Vegas but not so much for racing."
This is the reason given by the stewards as to why Carlos Sainz has been handed that grid drop: "The stewards note that if they had the authority to grant a derogation in what they consider in this case to be to be mitigating, unusual and unfortunate circumstances, they would have done so, however the regulations do not allow such action."
According to Sky Sports, the stewards spent three hours trying to find a way around the rules so Sainz and Ferrari could avoid a penalty.

Talk about last-minute. Repairs on a hole on the pit entry outside the commentary boxes with 15 mins to go before the session.

Stephen Kelly: "Blip or Black Eye?" It's a full on knockout, F1 should never have gone to Vegas in the first place, useless and boring track which is only worth it for the 0.01% of people who can actually afford it. Madness we don't have a French or German GP and we have this.
Kayleigh: Absolutely foul to give Sainz an engine penalty for an incident created by the track!

Elvis will officiate, there are racing-themed decorations and the neon signs reads: 'Lights out and together we go'.
Who were the first couple to say 'I do'? Only 1997 world champion Jacques Villeneuve. The Canadian married his parter, Giulia Marra, in a ceremony before first practice.

For the Saturday night grand prix (Sunday morning in the UK), Pirelli have selected the softest compounds in the range for the 6.201km Strip circuit, which Pirelli’s motorsport director Mario Isola says "should guarantee good grip".
Teams can choose from the C3 (white, hard), C4 (yellow, medium) and C5 (red, soft).

Matthew: See, this is why you check the track is all good before you let the cars go out! Personally I don't think this is a good track. It's more for show than actual racing.
Tom: Could have been a lot more dangerous than a black eye. This sort of thing has happened before, but always on street circuits. Almost as if a public road wasn’t built to handle a 200+ mph race car. Get back to actual tracks!

It's the belief here that the session has a hard stop at 04:00 local time. So if there are further delays, that would shorten the session.
The grandstands are empty now. Second practice will get going at 02:30am local time!
Image source, Tilke Design and ArchitectsThis little piggy has been naughty. Let's see if it can behave itself in second practice.
It looks like a hog roast, but all the big Strip landmarks will be taken in during the 50-lap race including Caesars Palace, the Bellagio (including the famous fountains) and the brand new MSG Sphere.
Average speeds for the 17-corner track are expected to match the Italian test at Monza, with Pirelli motorsport director Mario Isola anticipating a "very fast" Vegas thrill ride.
"We are expecting a high speed straight - very high speed," Isola told Bloomberg.
Fingers crossed we get to see some rapid laps.
