Aston Martin would not give details about what it called a minor accident, but said Stroll, the son of team owner Lawrence, expected a speedy recovery. “His fitness to return to track will be assessed daily and an update will be issued by the team ahead of the Bahrain Grand Prix,” they said.
Belgian Stoffel Vandoorne, Formula E champion, and Brazilian Felipe Drugovich, Formula 2 champion, are the team’s reserve drivers.
The other Aston Martin driver is Spanish Fernando Alonso, 41, a double world champion, who joined the team after leaving Alpine, owned by Renault.
“I had an unfortunate accident while training on the bike to prepare for the season,” Stroll was quoted as saying by the team.
“I am determined to get back in the car and am excited about the season ahead with the team. I am motivated to recover from this setback as soon as possible.”
Testing in Bahrain will take place from February 23-25, with the opening race on March 5.
