Lando Norris has been taken to a hospital for 'further precautionary investigations' after a heavy crash at the Las Vegas Grand Prix.
The McLaren driver was in P13 when he looked to lose control on just turn 14 of the race on the fourth lap, causing him to spin in to the barrier.
The British driver had recovered well from his starting P16 position after a poor performance at qualifying.
But - after previously criticising the condition of the surfaces in Vegas - this is now his first retirement in a race since the 2022 Brazilian GP.
Low temperatures combined with a brand new tarmac laid down with very little rubber meant none of the drivers had much grip.

The McLaren driver hit hard into the barriet after his rear axle locked and he spun out
The track temperature today was roughlly 16 degrees as opposed to a usual temperature of 50.
That meant all the drivers today faced a battle in keeping their tires warm to keep grip.
For Norris' crash in particular, the driver locked the rear axle as a result of the low grip and cold tyres.
The McLaren driver was a total passenger the moment his rear overtook his cockpit.
