This is why Aston Martin has no replacement for Stroll

Stroll will not participate in the Grand Prix of Spain, and a replacement cannot simply be called upon. To participate in the race, a driver must also have taken part in the qualifying for that particular race. Fernando Alonso will therefore be the only Aston Martin driver who has a shot at scoring points for the team tomorrow.

What about the races after that? The next race after the Grand Prix of Spain is the Grand Prix of Canada, Stroll's home race. Should Lance be unable to participate there, the question then becomes who the team chooses as a replacement for that race weekend.

The Canadian Grand Prix overlaps with the 24 Hours of Le Mans. Felipe Drugovich and Stoffel Vandoorne are Aston Martin's reserve drivers but both are participating in the prestigious 24-hour race. Since Drugovich is a guest driver in the LMP2 class, it makes sense for him to skip the race in France, to take part in the Canadian Grand Prix instead - that is, if Stroll is unable to compete in Montreal.

Valtteri Bottas is not an option. For instance, if McLaren needed a reserve driver, they could ask Mercedes to put Valtteri Bottas in the MCL39. But such a 'deal' is not in place with Aston Martin (Mercedes' customer team, ed.), Mercedes has confirmed to GPblog.

The American Jak Crawford (competing in Formula 2) is also a reserve driver for Aston Martin, but he then faces the issue of not having enough points for a super license and thus cannot race in Formula 1.
