Sainz and Ocon referred to stewards after Las Vegas damage

The stewards have been called to deliberate over Carlos Sainz and Esteban Ocon's cars after they sustained damage during the first free practice in Las Vegas.

A loose manhole cover caused the session to be abandoned after both cars were left with damage minutes into the session.

The fate of FP2 in Las Vegas is not yet known with the session currently delayed while a track inspection is carried out.

Following the incidents, the respective teams have been forced to make changes to the cars ahead of the remainder of the weekend.

For Sainz's Ferrari, the Italian squad has been forced to swap in a new Survival cell, Internal Combustion Engine, Energy Store and Control Electronics. Ocon's Alpine also requires a new survival cell.

The matter has been referred to the stewards as such changes would incur grid penalties under normal circumstances.
