Aston Martin said Stroll would miss the Spanish Grand Prix because he “had been experiencing pain in his hand and wrist”.
The team said Stroll’s medical consultant believed the discomfort was related to an operation he had in early 2023, when he broke both wrists in a cycling accident.
Stroll is to have an operation in an attempt to rectify the problem.
The situation puts his participation in his home race in Montreal on 13-15 June in doubt.
If Stroll were to miss the race, it is not clear who would replace him, as reserve drivers Felipe Drugovich and Stoffel Vandoorne are both racing at Le Mans on the same weekend.
Stroll was investigated by governing body the FIA after he failed to go to the driver weighing scales immediately after qualifying, as is required by the regulations.
The race stewards gave him an official warning for the omission.
The stewards’ verdict said: “We reviewed the video footage from the garage which showed the driver of Car 18 [Stroll] exiting the car and leaving the garage from the back and not proceeding through the pit lane as required.”
The stewards wrote that Stroll had sent them a letter explaining that “the reason for failing to immediately attend the weighing was because he was in pain and sought urgent medical attention for the pain.
“He attended the weigh-in and the media pen as soon as he was able to, before heading to the medical centre for further evaluation.”
This is not the first time Stroll has lost his temper as a result of a bad qualifying session.
In Qatar in 2023, he stormed out of the back of the garage and was involved in an altercation with his trainer as he left. He later apologised for the incident.
