Mercedes have been given permission to change their rear wing assembly for the second practice session in Brazil, as the investigation into the legality of the rear wing they used on Friday continues.
The rear wing Hamilton used in qualifying is currently impounded by the stewards, as they investigate whether it conforms with the Technical Regulations or not.
With the second practice session imminent, and a decision regarding that rear wing still to be made, Mercedes have been granted permission to run a different rear wing in FP2 to enable them to head out on track.
As the cars are in parc ferme conditions, Mercedes had to be given special permission by the stewards in order to run a different rear wing - the team confirmed this change in a statement to RacingNews365.com.
"We have been given written permission to replace it, as per the regulations," a spokesperson said.
This will allow Hamilton to go out on track for the second practice session, where the teams are not permitted to make any setup changes under the rules of the Sprint Qualifying format.
